What is 4026 IC in Digital Counters

Integrated Circuits play a vital role in the field of circuits and electronics. These are the combination of different fundamental devices in very specific yet functional ways. The 4026 belongs to the family of the Integrated Circuits in the series of 4000. The 4026 IC is introduced as:

"The 4026 is CMOS seven Segment counter  integrated Circuit that is the designed in decade Based and counts in the decimal digits and consist of total 16 pins." 

The output of the 4026 digital counter is usually fed into a 7 segment display Light Emitting Diode that shows the counter output of the 4026 IC Counter. Being an IC, the pins of the 4026 Digital counter IC are very specific. By looking at the block diagram of 4026 IC Counter, we can generate a table that shows us the proper configuration of the 4026 IC.

Pin Number	Pin Name	Description of the Pin
1	Clock (CLK)	With each positive clock Pulse, it increments the counter.
2	CI (Clock Inhibit)	It is the Active high. When high, the counter freezes. When low, the clock pulse increments 7 segments.
3	DE (Display Enable)	Chip will ON when this is high and vise versa.
4	DEO (Display Enable Out)	Chaining 4026s.
5	CO (Carry Out)	It completes a single cycle after every 10 clock input cycles. It is used to change the clock manner of 1 counter into a multi counter.
6	F	This Pin is connected to ‘f’ of the 7 segment.
7	G	This pin is connected to ‘g’ of the 7 segment.
8	VSS	It is the Ground PIN
9	D	It is Connected to ‘d’ of the 7 segment.
10	A	It connects with the  ‘a’ Pin of the 7 segment.
11	E	It Connects the ‘e’ of the 7 segment with it.
12	B	It Connects to the  ‘b’ of the 7 segment.
13	C	It is Connected to ‘c’ of the 7 segment.
14	UCS ( Un-gated C-Segment)	It is an output for the seven-segment's C input that is not affected by the input of  DE . When the count is 2, it is high.
15	RST (Reset)	Reset the counter to 0 when HIGH. Hence it is Active High.
16	VDD	Power supply PIN

In out experiment, we'll set all these pins according to our requirements to get the desired output. but some of the points here are pending to discuss. You may noticed the functioning of 6, 7, 9 to 13 pins of 4026 IC Counter. Let's have a look what does we mean by the description.

Seven Segment Display with 4026 IC Counter

This is the electronic device that is used to show the output of the counters such as 4026 IC. We define the Seven Segment Display as:

"The Seven Segment Display is a collection of 8 Light Emitting Diodes in a rectangular fashion that is an output device used to display the outcomes of different counters." 

For the convenience of connections, each LED of the Seven Segment Display is named i alphabetically and hence each pin of Seven Segment Display is connected with pins of 4026 IC Counter. 

Working of 4026 IC Digital Counter

1. The Simulation of the circuit starts with the pulse generation at the Clock Pulse. These Pulses enters the BC547 MOSFET that regulates the pulses.
2. The LED Connected to the BC547 MOSFET blink and we get the idea about the speed of the Pulse Generation.
3. The Pulse enters the 4026 IC Counter and the counter Passes these pulses to the seven segment Display device.
4. Each pulse from the 4026 IC power ups the respected LED of the seven segment display in a specific manner that we always get the digit as a result.
5. The power is then Grounded connected to the seven segment display terminal.
6. The output can be reset to the initial state with the button. This button is connected to the reset terminal of 4026 IC.

Automatic Light Detector using LDR in Proteus

Hello Learners! We hope you are fine. Welcome to The Engineering Projects. The Automatic Light Detector is the device that automatically senses the light incident on it. Let's have a glance about the main points of discussion:

1. What is Automatic Light Detector?
2. What are different components and their functions in the Automatic Light Detector?
3. How does the circuit of Automatic Light Detector works?
4. How can we implement the circuit of Automatic Light Detector in Proteus ISIS?

Moreover, you'll have some chunks of interesting information in DID YOU KNOW sections.

Automatic Light Detector

Automatic Light detectors or automatic Light sensors are interesting devices. They have special mechanism in their circuit that senses the density of the light and after that, the mechanism automatically changes the condition of the Light detector according to the need. Thus an Automatic Light Detector is defines as:

"An Automatic Light Detector are the photoelectrical devices that works with the principle of flow of current and turn the circuit components on/off automatically when the light incidents on its circuit." 

The Automatic Light Sensor is an elementary electrical component Which is usually used to handle the electrical Appliances such as coolers, fans, lights etc. without any manual efforts. In this way the manually switching of the electrical components can be controlled more easily. Their working depends upon the intensity of light around them.

DID YOU KNOW????????????

A very simple and usual application of the Automatic Light Detector is the Automatic Street Lights system. Have you ever noticed that there are hundreds of street lights around you when you go for a ride. If someone had a duty to turn them on and off manually, even they have a combine circuit. But it would be a time taking job. Moreover, there will be more chance of energy wastage. But all the street light have the Automatic Light Detector system so that they turn on and off automatically.

Components of Automatic Light Detector

Prior to start the construction of the circuit, Let's have some brief about the components of the circuit for Automatic Light Detector. The circuit that we'll use depends upon the following components:

1. LDR
2. n-p-n Transistor
3. Simple
4. Variable resistor
5. Battery
6. LED

LDR in Automatic Light Detector

LDR or Light Dependent Resistor is the heart of Automatic Light Detector. These are the electronic components, made up of high resistance semi-conductor material, that detect the light and alter the operation of the whole circuit according to the type of the circuit. The LDR is passive and it does not produces any electrical energy. LDR are used in many cases because of their rugged nature. They are not sensitive to dirt and rough environment and therefore have a long life and can be used in outdoor lights. Other different types of Light Sensors are:

• Photodiode
• Photo-voltaic cells
• Photo-multiplier tubes
• Charged Couple Devices.

n-p-n Transistor BC647 in automatic Light Detector

The full form of n-p-n Transistor is the negative positive negative Transistor. In this type of  It is designed to pass electrons from emitter to collector. so the emitter "Emits" the electrons to the base. Obviously, in case of conventional current the current flows from the collector to the emitter. In this Circuit the base of the n-p-n Transistor is connected with the one end of variable resistor and the LRD, emitter is connected with the battery and the variable resistor and the collector is joined with the LED directly.

Resistors in Automatic Light Detector

Resistors are the passive devices consist of two terminals and the body. These are the electric components that are widely use to resist the sudden flow of electricity through a circuit. In many case, they are life saving for the components of the circuits. Other uses of resistors includes:

• Bias active elements
• Terminate Transmission lines
• Adjust signal level to device voltage.

The Automatic Light Detector uses two types of resistors:

1. Simple Resistor
2. Variable Resistor

The key difference between them in the circuit of Automatic Light Detector is, the resistance (Resisting ability) of variable resistor may be change according to the need of time.

Battery in ALD

A battery is the Lead-acid type cell that consists of the collection of four 1.5V D battery cells. It gives the energy to the components of the circuit for their functioning. The Battery will give the power to the circuit so that the flow of the current will illuminate the light or pass through the LDR.

LED ALD

The full form of LED is the Light Emitting Diode. It is a simple device used in our daily life as well that illuminates when the energy in the form of current or voltage is applied to it. In our circuit, the main function is the turning the on/off of this LED.

Working of the Automatic Light Detector Circuit

When we look at the circuit of Automatic Light Detector, we found that the whole working start from a 6v DC Battery. This battery give the energy to the circuits. At the day-time the LDR has a low resistance of about 100 ohms. In this case, the resistance of the LDR is less than the other devices of the circuits and we all know that:

The current passes through the path that shows the less resistive path.

The power from the battery passes through it and then from the variable resistor easily. At the Night-time when the light, incidents on the LRD is less , the resistance of LDR increases to a high level of approximately 20 mega ohm. Due to this high resistance, the LDR act as an open circuit and does not allow the flow of current through it. For this condition, the current will flow from other components of the circuit and hence the current enters o the base of the n-p-n Transistor BC545. This allows the current to pass from the LED and hence it illuminates.

Automatic Light Detector in Proteus

Before any practical implementation, one should always check it in the simulation for practice. Luckily, for our experiment, the Proteus contain all the components through which we can check the functionality of Automatic Light Detector. Fire up you Proteus software and Choose the components one after the other. Once selected, design a circuit of Automatic Light Detector by following these simple steps.

• Get the Components from the Pick Library and arrange them according to the Circuit diagram.

• Double tap the each components except n-p-n transistor and change their values according to the table given below:

  Component	Value
  Resistor	470 ohms
  Variable Resistor	10k ohms (At the start)
  Battery	6 volts

• Connect all the components by the mean of connecting wires.
• Simulate the circuit.

• Check the working of circuit by changing the values of the Light Detector Resistor.
• Above 5.1 value of the LDR, the LED illuminates because of high resistance, the current flows through the LED.
• Below 5.1, the LED remains off.

Applications of Automatic Light Detector

Some of the practical applications of Automatic Light Detector are given below;

1. Automatic Light system.
2. Light measuring instruments.
3. Relative distance devices.
4. Alarm system.
5. Security Systems.

Truss today we learned about the Automatic Light Detector/sensor. we saw what components are present in its circuit, how the system works and how can we implement it in the Proteus software. We hope you had an interesting piece of study through our article.

Boost Converter using MOSFET IRFZ44N in Proteus

Hello Learner! Welcome to another exciting experiment at The Engineering Projects. We hope you are having a great day. In this lecture, we'll seek information about the Boost Converter Circuit from scratch to result in quick and easy steps. So, if you don't know about the experiment then don't worry because every Expert was once a Beginner. We'll talk about the following topics:

1. What is IRFZ44N MOSFET Boost Converter?
2. What is the brief introduction of components of circuit?
3. How can we implement the IRFZ44N MOSFET to design circuit of Boost Converter?

You will know some useful information about the topic in the DID YOU KNOW sections.

IRFZ44N MOSFET Boost Converter

During the experimentation of electronic circuits, we often face the situation when we have to amplify the voltage signals or voltage power. For example, when we need the 12V in the experiment but we have just 9V battery or any such case. There are many ways to tackle such condition but it requires a lot of energy and steps. But when we search our solution in the world of Switched Mode  DC-DC Converters, we find a very easy and simple solution of our problem in the form of IRFZ44N MOSFET Boost Converter. NOTE: One can make the BOOST Converter using one of many MOSFETs but we have focus on IRFZ44N due to its best result. Prior to start the experiment, it is compulsory to have some basic information about the circuit. We define the IRFZ44N MOSFET Boost Converter as:

The Boost Converter is the Electronic device that uses a MOSFET (IRFZ44N MOSFET in our case) to convert it's Low input DC Power into High output DC power.

The IRFZ44N MOSFET Boost Converter is a switched-mode power supply and this is consist of at least two semi-conductor device and minimum one energy storage element.

DID YOU KNOW????????????????

We call IRFZ44N MOSFET Boost Converter as Switched Mode Devices because basically, they are the semi-conductor Switches that turns their condition On and Off very rapidly.

Components of IRFZ44N MOSFET Boost Converter

Throughout the experiment, we'll use the components that will convert the low level Voltages into High Level Voltages. A brief introduction of the components is given next:

IRFZ44N MOSFET

The IRFZ44N Metal Oxide Semi-Conductor Field Effect Transistor is used as a switch in the IRFZ44N MOSFET Boost Converter. The main reason behind this is one can change its conductivity by changing its Gate Voltage and hence we can use it as a switch. This is one of the key procedure to amplify the voltages in the IRFZ44N MOSFET Boost Converter.

Inductor

We all know an inductor is a passive two- terminal magnetic storage device that stores the energy due to its coiled shape. Due to its storage capability, it resists the sudden change of current in the IRFZ44N MOSFET Boost Converter. In this way, it work as a stabilizer in the circuit and play an important role.

Diode

A diode is a reverse biased component of the IRFZ44N MOSFET Boost Converter. It is designed in such a way that it allow the flow of current only in one direction. Hence, in the IRFZ44N MOSFET Boost Converter the Diode allow the flow of current from inductor to the capacitor in only in the condition when it is forward biased.

Capacitor

A capacitor is a device that stores the energy in the form of charges. In IRFZ44N MOSFET Boost Converter when the Switch is turned off, the diode does not allow the flow of current through the capacitor. This is the condition when the stores energy in the form of charges from capacitor is used and the capacitor then works as the source of energy in IRFZ44N MOSFET Boost Converter.

Output graph

Before this we saw the components that we'll use in the formation of circuit, but we require other components as well to examine the result and working. We examine the result through an output device that shows us the result in the form of graph. For our experiment, we'll use analogue analysis graph for the output.

IRFZ44N MOSFET Characteristic Curves in Proteus ISIS

Hello Learners, Welcome to another useful tutorial at The Engineering Projects. In the world of electronics and circuits, many useful devices are designed that can minimize the requirement of large and complex circuits. At the Present time, we are working at such a device works very near to the base of many circuits i.e, IRFZ44N MOSFET. We'll  approach to the answers of following Questions:

1. What is IRFZ44N MOSFET?
2. How is the Structure of IRFZ44N MOSFET?
3. What is the working mechanism for the IRFZ44N MOSFET?
4. How can we find the characteristics of IRFZ44N MOSFET in Proteus ISIS?

You will have some important chunks of information about the topic in DID YOU KNOW sections.

What is IRFZ44N MOSFET

As you can see, MOSFET is a acronym of Metal Oxide Silicon Field Effect Transistor. We introduce the IRFZ44N MOSFET as:

IRFZ44N is an important type of N-type MOSFET that consist of three pins, have a hgh Drain current and a low Rds Values.

It is the type of IGFET( Isolated Gate Field Effect Transistors). A large amount of MOSFETs are used as switch every year. When we compare it with BJT , we find that it requires almost not current to control the load current unlike BJT. If you want in-depth study on this mosfet then you should have a look at IRFZ44N Datasheet.

DID YOU KNOW ???

MOSFET is a semi-conductor device that is Fabricated by the Controlled oxidation of Semi-conductors (Silicon in most case). It can work in both modes of operations i.e, Depletion and enchantment.

Structure of IRFZ44N MOSFET

When we observe the IRFZ44N MOSFET we find that it consist of mainly three pins as described below:

Pin Number	Pin Name	Role
1	Gate	Controls biasing
2	Drain	Current input
3	Source	Current Output

Vgs: The IRFZ44N MOSFET is a voltage controlled device that means it can be turned on and off when we apply a required threshold Voltage. This voltage is termed as Vgs. Vds: It is the absolute Maximum Voltage of IRFZ44N MOSFET between Drain and Source. This is salient characteristic of IRFZ44N MOSFET because during the operation of IRFZ44N MOSFET Drain-source voltage should kept less than maximum rated value. Here D Stands for Drain and S stands for Source. Ids: It is the amount of current that passes from Vds to the IRFZ44N MOSFET. The direction of this current is important during the Operations of IRFZ44N MOSFET.

DID YOU KNOW ???

The MOSFET is a better version of Junction Field Effect Transistor. Due to the limitation of JFET for the conduction in one side only ( some time it is the advantage), the Designers made a new type of Transistor that can change the conductivity when the amount of applied voltage is change and named them as MOSFET.

Characteristic Curve of IRFZ44N MOSFET

The quality and the suitability of any transistor is checked through its characteristic curve. The characteristic curve of IRFZ44N MOSFET have two phases.

1. Depletion Mode
2. Enhancement Mode

Depletion Mode

In this mode the Transistor is closed during the zero bias voltage at gate terminal. Hence the IRFZ44N MOSFET  is said to be switched ON. The channel width increases when the Gate Voltage is increased to the positive side. in return, the current Ids increases. During the situation when Gate voltage's value is decreased, the Width of the channel decreases and Ids follows the same rule.

DID YOU KNOW ???

The IRFZ44N MOSFET is also known as the Power MOSFET. It is 22oAB through hole package that has three pins. The top metal tab is also called the drain because both of them are same.

Enhancement Mode

This mode is usually considered as normally open switch as the transistor does not conduct the current when the Gate Voltage is zero. If we apply a positive voltage to the gate then a Drain current follows through the Gate. The Enhancement mode of IRFZ44N MOSFET  enhances the channel because when the Drain current's value is increased the channel width increase and the decrement of the width is for vise versa.

IRFZ44N MOSFET Characteristic Curve in Proteus ISIS

To understand the whole discussion mentioned above, Let's make a characteristic Curve of IRFZ44N MOSFET in Proteus ISIS. To do this, just follow the simple steps given next:

• Power up your Proteus software.
• Go to Pick Library by pressing the "P" button given at the left side of the screen.

• Choose Ground Terminal and set it just below the IRFZ44N MOSFET.
• Go to Generation mode and select DC.

• Set one DC probe at the left of the irfz44n MOSFET and take another and set it at the upper side of irfz44n MOSFET.
• Connect at the components set until now with the Help of Connecting wires.

• Select the current probe and set it just after the Vds. Make sure its direction is toward the irfz44n MOSFET.
• Go to Graph Mode>Transfer and set a Transfer Graph just after the Circuit.

• Right Click the Graph>Edit Properties>Set the Vds as Source 1>Set Vgs as Source 2>click Ok.
• Right Click the Graph>Add Trace>Set Ids as the Probe>Click ok.
• Right Click the Graph>Simulate.
• You will Get the required output:

Hence, in this article, we learned about the IRFZ44N MOSFET, we saw the introduction of IRFZ44N MOSFET, Learned about the structure of IRFZ44N MOSFET, saw some important concepts about the IRFZ44N MOSFET and performed a Practical Implementation of IRFZ44N MOSFET for the Characteristic Curves in Proteus ISIS.

3. How can we implement the 2 bit Full Subtractor in Proteus ISIS?

You will also learn some important chunks of information in the DID YOU KNOW sections.

2 bit Full Subtractors

A full Subtractor works really well in the processor. We’ll talk about it function but before that have a look at its definition:

• 2 bit Full Subtractor is a Combinational Logic that contain three Inputs and Two outputs and perform the function of Subtraction with two bits.
• Minuend: The 1st input is called the Minuend used to take the bit from which the 2nd value will be Subtracted.
• Subtrahend: It is called the 2nd input that is subtracted from Minuend.
• Borrow in: It is the third input that is use to take the value of the Previous borrow and we’ll denote it as B(in) here.

• Borrow Out: The Borrow out is symbolized as B(out) and it the resultant borrow that the output Terminal shows.
• Difference: This is the main result that was the concern of the experiment and its value totally depends upon the binary subtraction rules.

DID YOU KNOW?????????????????

There is another circuit called Half Subtractor that is used for the subtraction of bits but the foremost disadvantage of that circuit was its inability to work with the borrow taken in the previous calculation and the designers worked for another better Subtractors.

Truth Table of 2-bit Full Subtractor

If you know about the Concept of binary subtraction, you can use your knowledge to generate a Truth Table of 2 bit  Full Subtractor so that one can design a feasible Circuit of 2 bit Full Subtractor. The Table contain all the records that can be possible for our experiment and its result into the bargain. Thus the Truth Table for the Full Subtractor is shows as:

Minuend	Subtrahend	B(in)	Difference	B(out)
0	0	0	0	1
0	0	1	1	1
0	1	0	1	1
0	1	1	0	1
1	0	0	1	0
1	0	1	0	0
1	1	0	0	0
1	1	1	1	1

Working Mechanism of 2 bit Full Subtractor

When we observe the Circuit of 2 bit Full Subtractor, we found that it is combination of two circuits of Half subtractors and the output of each circuit is then fed into an OR Gate through which we get the output of borrow. We have two types of outputs in the 2 bit  Full Subtractor:

1. Difference
2. Borrow

DID YOU KNOW?????????????????

The Full Subtractor is the one of the most fundamental Logic circuits of that are used for two bit subtraction in many computing system.

Let's have a look at the procedure of calculation of both.

Difference

The binary subtraction is similar to the decimal subtraction but it works with only two digits called 0 and 1 instead of 1 to 10 in the decimal. When we examine the answer of the bit difference while using a Truth Table in the Half Subtractor circuit, we found that it is identical to the XOR Gate. Therefore we use a XOR Gate for the Difference that is introduced as:

The type of Logic Circuit that gives the output HIGH only when both its inputs have inverse value to each other and vise versa. 

Thus the truth table for the XOR Gate is given as:

A	B	A XOR B
0	0	0
0	1	1
1	0	1
1	1	0

The output of the XOR Gate is Fed into another XOR Gate for the Full subtraction which has the connection of a Borrow Input B(in) at its Second input.

DID YOU KNOW???????????????

The Application of the  Full Subtractor is found in the ALU of computer where they are responsible for the Graphic application to decrease the difficulty in the CPU and GPU.

Borrow

Many times, the situation arrives when the Minuend<Subtrahend and in this way, the circuit need to borrow a bit from the bit presented just after it. The Full Subtractor do this through the AND Gate that contain a NOT Gate at its one end. For full Subtractor, this arrangement is again fed into the duplicated circuit and the both the outputs of this AND Gate is fed into the OR Gate that gives us the Borrow(out).

T Flip Flop Circuit Diagram in Proteus ISIS

Hey Learners! I welcome you on the behalf of The Engineering Projects. I hope you are doing Great. If you are seeking for the best information about the T Flip Flop along with some small concepts and the Practical Performance, then you are at the right article. In this session you will get the following topics:

• What are T Flip Flops?
• What are the Functions of Preset and Clear Input in T Flip Flop?
• How can we Design the Truth Table of T Flip Flop?
• How can you perform the T Flip Flop simulation in very simple and useful way?

Moreover, you will also get some pieces of information in DID YOU KNOW sections. so without wasting time, lets Jump into the answer of 1st Question.

T Flip Flop

T Flip Flop belongs to the family of Flip Flops and Latches and we define the T Flip Flop as:

"T Flip Flops are bi-stable sequential Logic Circuits that are the modification of SR Flip Flops and contain just one input called T and two outputs called Q and Q' and a Clock input in the circuit. "

The Circuit is similar to the JK Flip Flop but the inputs are connected with the same Logic toggle and we control the Circuit with the help of Preset and Clear inputs. Furthermore, a Clock is used to synchronize the signals. we'll talk about this feature in upcoming sections.

DID YOU KNOW????????????????

The T Flip Flop is the modification in the JK Flip Flop that has two inputs and two outputs.

Function of Preset and Clear inputs in T Flip Flops

The Function of Preset and Clear is important. Both of these are the Synchronous Inputs. By saying this, we mean that these inputs are out of the Influence of the Clock. We change the values of these inputs, the working mechanism change according to the conditions. It seems that these inputs are not important yet they are important because one can use the circuit in different ways according to the requirements. In out Circuit and Truth Table, we denote the Preset as "P" and Clear as "C". You can Make a circuit without these inputs but it may have less functionality and working.

Working mechanism of T Flip Flop

The T Flip Flop work very similar to the JK Flip Flop but it has the difference that it can toggle with the situation of JK Flip Flop. Let's have a look at the situations in T Flip Flops.

DID YOU KNOW?????????????????

The T Flip Flops also called the Toggle Flip Flops. the toggling action is the presses in which the circuit is changed from 1 to 0 and vise versa.

When P=1 and C=0

In this condition, the Circuit is in the Set Condition. It means, the condition of Q will be same as the T . if T=1 then Q=1 and vise versa.

When P=0,C=1

This is the condition where the Circuit is in the RESET condition. The Q remains HIGH irrespective of the value of T. Toggle input have the influence on the Q'. the Output Q' follows the same condition as the T.

When P=0,C=0

In this Condition, the value of Toggle input does not have any effect on the Output, they remain open always.

When P=1,C=1

for this situation. the output is of Q is HIGH for a while then low and Q' is High.

DID YOU KNOW?????????????????

You can also use an IC for the T Flip Flop. It will be more easy and effective but it has a fixed working that is not good for the learning purpose.

T Flip Flop Truth Table

If we look at the discussion above, we'll get an idea that the T Flip Flop work according to the values of synchronous Inputs. Here's the T Flip Flop Truth Table:  

Condition	P	C	CLK	T	Q	Q’
SET	1	0	High	0	0	1
	1	0	High	1	1	1
Reset	0	1	High	0	1	0
	0	1	High	1	1	1
invalid	0	0	High	0	1	1
			High	1
Invalid	1	1	High	0	0	1
			High	1	1	1

Hence, now we have a great idea what does T Flip Flop do. Let's design the circuit of T Flip Flop in Proteus using all these concepts.

DID YOU KNOW??????????????????

When Clock is LOW, one can examine a totally different behavior of the Circuit.

T Flip Flop Circuit Diagram in Proteus ISIS

• Now we will design T Flip Flop Circuit Diagram in Proteus Software.
• Here's the components list, which will be required for this simulation:

Components Required

1. 3 input NAND Gate.
2. 2 Input NAND Gate.
3. Logic Toggle.
4. LED-red.
5. Ground Terminal.
6. Connecting Wires.

• Choose the 1st four components from the Pick Library through "P" Button one after the other.
• Set Four 3 input NAND Gate at the screen vertically just like shown in the image below:

 

• Take two Logic Toggles and set them just before the Gate 1 and one in between Gate 1 and 2 one by one.
• Take 1 logic Toggle and set it just upper side of the system.
• Repeat the step with the lower area of the Circuit.
• Get the LED and place it after the Gate Q.
• Repeat the step with the Q' Gate.
• Grab the Ground Terminal From the Terminal Mode>Ground present at the left side of screen and connect 1 with the end of LED of Q and Q'.
• Connect all the components with the help of connecting wires according to the image given below:

 

• Change the Values at the Logic toggles and observe the result.

DID YOU KNOW?????????????????

One can use the Clock Terminal present in the pick Library. But it will be difficult to understand the conditions and outputs because it is less demonstrative.

Truss, today we saw what are the T Flip Flops, How does Preset and Clear work in the T Flip Flops, how can we design the Truth Table of T Flip Flop and how can we design the whole simulation of T Flip Flop in Proteus ISIS. If you want to learn more about the circuits and simulation of Logical and Electronic Circuits, you can check our other tutorials and experiments as well.

D-Type Flip Flop Circuit Diagrams in Proteus

Hey Mentees! Welcome from the team of The Engineering Projects. We hope You are having a reproductive day. To add more reproduction, let's learn another Logical Circuit from scratch. In this Tutorial, we'll grasp the following topics:

1. What are D-Type Flip Flop?
2. Which is the IC of D Flip Flop in Proteus ISIS?
3. How is the working of D Flip Flop?
4. How can we design the Truth Table of D Flip Flop?
5. How can we Perform the formation of D Flip Flops in Proteus ISIS?

Moreover, we'll have small chunks of information in DID YOU KNOW Sections. At this instance, Let's start the learning.

D-Type Flip Flops

D-Type Flip Flops are important Logical Circuits and we Introduce it as:

"The D-Type Flip Flop is a type of Flip Flop that captures the value of D input for a specific time of the Clock edge and show the output according to the value of D at that time."

D-Type Flip Flops have the ability to Latch or delay the DATA inputs and therefore are the improved version of the SR Flip Flop (In which the data shows the Invalid output when the inputs are HIGH) . Recall that Flip Flops are the Logical Circuits that can hold and store the data in the form of bits and are important building blocks of many of electronic devices and circuits.

DID YOU KNOW???????????????????????? The D Flip Flop is also known as the Data Flip Flop.

When we observe the circuit of D Flip Flop we observe 2 Important points in the D flip Flops:

1. The D Flip Flop is the circuit of active High SR Flip Flop that have the S and R inputs connected together with an invertor gate so that both S  and R (looking with the point of view of SR Flip Flop) will always have the opposite state to each other.
2. The circuit has only one input called D input and it always has a clock that has one of the major effect at the output of D Flip Flop.

D Flip Flop IC

IC's play a magical role in the world of electronics. They make the circuit so simple and decrease the chances of the errors in the circuit. for D Flip Flop, the IC Used has a number CD4013 and for better understanding, D Flip Flop IC named 4013 is shown in the Proteus software in the image below: The S and R are the additional pins to use it for the higher level Experiments. Yet for the simplicity and core information, we'll use Logic Gates when we'll perform in the practical section.

Working of D Flip Flop

In the working of D type Flip Flop, we observe that the D is the only input of the D Flip Flop. yet, the Clock also has the effect in the output of the circuit. Due to the Latched Circuit of Flip Flops, all this discussion would be pointless if we took the concept in the mind that at every pulse, the data of the Flip Flop is changed. Truss, we use an Enabler or Clock in the Circuit through which we can separate the circuit from the input at the instance of our will. When clock is HIGH: Thus, when the D is set HIGH the circuit is said to be in the "Set" State. By the same token, when the D input is LOW the circuit is said to be in the "Reset" position. Unlike SR Flip Flop, the output Q is same as the value of D input and Q' is the vise versa. When Clock is LOW: During the operation when the Clock or Enable input is LOW, any value at the D does not have any effect on the circuit's output. This position is called the "Don't Care" State of D Flip Flop.

Truth Table of D Flip Flop

Based upon the Concepts given above, one can easily design the Truth Table of the D Flip Flop. Let's have a look at the Truth Table.

Inputs		Output
CLK	D	Q	Q’
0	X	No Change
1	0	0	1
1	1	1	0

For the purpose of best understanding, we are going to check these concepts and the circuit information in the simulation Software. We are using the Proteus ISIS here.

Performance of D Flip Flop i Proteus ISIS

To perform the experiment in the software, just follow the simple steps given next.

Material Required

1. NAND Gate
2. NOT Gate
3. Logic Toggle
4. LED-RED
5. Ground Terminal
6. Connecting wires

• Fire up your Proteus ISIS.
• Pop the "P" button present at the screen and Write the name of 1st four devices and select them one after the other.
• Arrange four NAND gates and the inverter gate (NOT Gate) at the working area just according to the image given below:

• Take Logic Toggles and arrange them just at the left side of the system.
• Get the LED's for the output and connect one of them with the output of switch Q and Q'.
• Go to Terminal mode>Ground, attach the one ground Terminal with each the LEDs.
• Connect all the devices according to the diagram given next:

• Change the value of the Clock and observe does the value of the output change?
• Turning the LED on means the output is HIGH and vise versa.
• For convenience, the D Flip Flop can also be obtained by using a NAND as NOT in the Circuit as shown in figure:

DID YOU KNOW?????????????

In real life, the Clock is used in the place of Logic Gate (as shown in the image above) because it automatically changes the direction and change the output of the D Flip Flop. 

NOTE: You can also use the Logic Probe instead of the Grounded LED. Truss, in this session, we saw what are the D Flip Flops, how does they work, how an we design the Truth Table of D Flip Flop and how can we perform it practically in Proteus ISIS. In the next session, we'll know what are T Flip Flop and how is its Simulation in Proteus ISIS.

Master Slave JK Flip Flops in Proteus ISIS

Hey pals! I wish you are doing great. Welcome to a new lesson about the Digital Logic Circuits in The Engineering Projects. In the past tutorials, we Designed the Basic JK Flip Flop. Today, we'll talk about the following Points:

1. What are JK Flip Flops?
2. What are the Master Slave Flip Flops?
3. How does the Circuit of Master Slave Flip Flop looks?
4. How types of JK Flip Flop different from each other?
5. How does the simulation of Master JK Flip Flip take place in Proteus ISIS?

Moreover, we'll also learn some key concepts in DID YOU KNOW portions. Yet Let's recall some points about the topic.  Flip Flops are the building block of a huge number of electronic systems and devices. A Flip Flop is a Digital circuit that can take the bits as input, work with the bits, Store the bits and can output the bits. it has four basic types and at the moment we are discussing the JK Flip Flops.

DID YOU KNOW????????????

The basic JK Flip Flops face a condition where when both the Inputs are HIGH and the Clock remains HIGH for a long time, then the output of JK Flip Flop becomes uncertain and this situation is called Race around Condition in JK Flip Flops..

JK Flip Flops

As discussed in the Previous tutorial , we define the JK Flip Flops as:

"The JK Flip Flops are the Modification of Set-Reset Flip Flops that contain two outputs and are able to work with the Invalid Condition of Flip Flops."

There are mainly two types of JK Flip Flops:

1. Basic JK Flip Flops
2. Master Slave JK Flip Flops.

The main focus of this tutorial is Master JK Flip Flops so lets find what are they.

Master Slave JK Flip Flops

The Master Slave JK Flip Flops are considered better than Basic JK Flop and we define them as:

"Master Slave JK Flip Flop is two input two output sequential Logic Circuits that are the Combination of two Basic JK Flip Flops and  work well even in Race around Condition of JK Flip Flops."

In Master Slave JK Flip Flops there are two JK Flip Flops that are connected in series. The 1st JK Flip flop is called the "Master" circuit and the other is called the "Slave" circuit. The output of the Master Circuit is connected with the inputs of Slave circuits. At the same token, the output from the Slave Circuit are then fed into the input terminals of Master Circuit. The circuit also contain an Invertor that is Connected with the clock and slave circuit in such a way that the Slave circuit always contain the inverting clock signal as the master circuit. Hence when Master circuit get the clock HIGH, then the slave circuit get the LOW and vise Versa.

Difference of Basic JK Flip Flop and Master Slave JK Flip Flop

Both of the circuits belongs to the same family but they are different in many ways:

1. Basic JK Flip Flop contain only one circuit but Master Slave JK Flip Flop contains two.
2. The Basic JK Flip Flop have the Race around condition but Master Slave does not.
3. Basic JK Flip Flop is less complex than Master Slave JK Flip Flop.
4. Basic JK Flip Flop is less used than Master Slave JK Flip Flop.
5. Basic JK Flip Flop does not require any NOT Gate but Master JK Flip Flop use it.

Circuit of Master Slave JK Flip Flop

If we talk about the Circuit of the JK Flip Flop then it is always convenient to use the IC presented in Proteus ISIS. We'll show you the Circuit of Master Slave through ISIS but for the best concept and the working of the Circuit, we'll demonstrate the Logic Gate Circuit of Master Slave JK Flip Flop during the Simulation. Let's have a look at the circuit of Master Slave JK Flip Flop with IC:

DID YOU KNOW???????????

When the condition of Master Slave Flip Flop is J=1 and K=1 then the values at Q  and Q' remains change according to the flow of clock.

Working Mechanism of JK Flip Flops

It is important to understand how Master Slave Flip Flop works. When the clock Pulse is set to be high, the circuit of Slave is isolated. The Slave circuit remains isolated until the Clock is high. At this position, the J and K have an effect at the output of the whole circuit. When we set the J as LOW and S as HIGH. The output of Switch 4 (Look at the picture below) will goes to the 2nd Input of switch 6. In this Condition, the Slave circuit copies the Master circuit. Similarly, when you change the values of J and K then you will Get different outputs according to the condition of clock.

Simulation od Master Slave JK Flip Flop in Proteus ISIS

• Connect the whole system through wires as reported by the following picture:

NOTE: You can also use the CLOCK instead of the Logic toggles in the experiment but this was not suitable for the demonstration purpose for me.

• Change the values of the toggle J,K and CLK one after the other to check the outputs.

This is the required circuit. Truss today we saw what are the Flip Flops, what are the JK Flip Flops. We saw the types of JK Flip Flops and leaned how can we perform the Practical simulation of Master Slave JK Flip Flops.

JK Flip Flop Circuit Diagram in Proteus

Hello Learner! I hope you are doing great. Welcome to another tutorial at The Engineering Projects. This blog is the part of series we have stated about the Digital Logic Circuits. Previous to this, we learned Implementation of SK Flip Flops in Proteus. at the present day, we'll seek the knowledge about the following points:

1. What are Flip Flops?
2. What are JK Flip Flops?
3. How can we record the Truth Table of JK Flip Flops?
4. What is the Procedure to Construct the circuit of JK Flip Flop through Logic Gates and IC circuit?

Moreover, we'll also have some useful bits of Information in Did you know Sections. Let' see the explanation of the concepts given above.

Flip Flops

The Flip Flops are the building blocks of many of  the Electronic Circuits. We define the Flip Flops as:

"The Flip Flops are the type of sequential Logic Circuits that are mainly made through the Logic Circuits and have the ability to receive, store, and show the output in the form of binary bits i.e, 1 and 0."

There are mainly four types of Flip Flops:

1. SR Flip Flops
2. JK Flip Flops
3. D Flip Flops
4. T Flip Flops

The main focus of this blog is JK Flip Flop so we'll discuss them in detail.

JK Flip Flops

JK flip Flops are the sequential Circuits and are the very much similar to SR Flip Flops. We introduce the JK Flip Flips as:

"The JK Flip Flops are the Universal Flip Flops containing two inputs, two outputs and a Clock in the Circuit. They have e the ability to avoid the invalid or Illegal condition of the Flip Flops."

The name of the inputs are said to be J and K respectively. Unlike SR Flip Flops ( where S stands for Set and R stands for Reset) the inputs of JK Flip Flops are titled autonomously. Somehow, related to the inventor of the JK Flip Flop "Jack Kilby".

DID YO KNOW???????????

JK Flip Flops are useful in many ways as: They have Low power dissipation. They are much Faster than their sibling Flip Flops.

]The output of the JK Flip Flops are named as Q and Q'. As the name implies , both the Outputs are opposite to each other. When Q is HIGH , the Q' is Low and same is the case with the opposite condition. The Truth Table Of JK Flip Flop is given next:

CLOCK	J	K	Q	Q’
High	0	0	Unchanged	Unchanged
Low			Unchanged	Unchanged
High	0	1	0	1
Low			0	1
High	1	0	1	0
Low			1	0
Low	1	1	1	0
High			0	1

There are two types of JK Flip Flop named as:

1. Basic JK Flip Flop.
2. Master-Slave JK Flip Flop.

Yet in this lesson, we'll make a clear idea about the Basic JK Flip Flop only. For best concepts, we'll not just observe the Circuit diagram of JK Flip Flop but we'll Construct a Circuit using different tools and Components in Proteus ISIS. We'll learn about the Formation of JK Flip Flop in two ways:

1. JK Flip Flop through Logic Gates.
2. JK Flip Flops through IC.

Rush toward your Proteus Software and learn how can you make this in just simple steps.

DID YOU KNOW????????????

The JK Flip Flops are the better version of SR Flip Flops and are better than those just using a NOR Gate.

Low			Unchanged	Unchanged	Unchanged	Unchanged
High	0	1	1	1	0	1
Low			1	1	0	1
High	1	0	1	1	1	0
Low			1	1	1	0
Low	1	1	1	1	1	0
High			1	1	0	1

Hence this is the required output.

JK Flip Flop IC (Integrated Circuit)

Due to the usability of JK Flip Flop, Proteus ISIS has added many JK Flip Flop IC. In this way, we do not need to design all the circuit. Instead we can simple using JK Flip Flop IC.Let's see how it will work:

Material Required

1. JK Flip Flop ( IC)
2. Logic Toggle
3. LED-red
4. Ground Terminal

• Place the JK Flip Flop IC at the working area.
• Connect Logic Toggles and clock at the respective ports.
• Add the Led at Q and Q' ports.
• Ground the LED's through Ground Terminals.

• Change the values of the Logic Toggles again and again and check that does you get the required output or not.

Easily available JK Flip Flop IC

Proteus also contain many other ICs of JK Flip Flop. Some of them are as follows:

1. 74LS107 that contain a Dual JK Flip Flop with CLEAR.
2. 4027B is an IC that is Dual JK Flip Flop.
3. 74LS73 contains Dual JK Flip Flop with CLEAR.
4. 74LS76 has Dual Flip Flop with PRESENT and CLEAR.

Truss, Today we recalled that what are the Flip Flops, what are its types, learned a great information about JK Flip Flops and designed its circuit in Proteus ISIS in two ways. Hopefully, you got the required pieces of particulars. in the next Lesson, we'll talk about the Master slave JK Flip Flops.
