Arduino Mini Library for Proteus V2.0

Update: Here's the latest version of this library: Arduino Mini Library for Proteus(V3.0).

---

Hi Guys! I welcome you on board. Today, I am going to share a new version of Arduino Mini Library for Proteus V2.0. This library is a successor of Arduino Mini Library for Proteus and the new Arduino Mini model is compact, small-sized, efficient, and more powerful.

In the previous post, I shared the Arduino UNO Library for Proteus V2.0, where we have simulated UNO in Proteus. In this tutorial, we will simulate Arduino Mini in Proteus. First, we will download this library and then will use it in our Proteus software to simulate Arduino Mini. Before we read further, let’s have a look at what is Arduino Mini.

What is Arduino Mini?

• Arduino Mini board is a small-sized, robust, application-type & powerful microcontroller board, based on an Atmega328 microcontroller.
• A total of 14 digital I/O pins are incorporated on the board, including 6 PWM pins.
• Moreover, there are 8 analog pins also available on the board.
• This board is quite small compared to Arduino Uno. It is 1/6^th of the size of the Uno board.

This was the little intro to Arduino Mini. Now let's start with its Proteus simulation:

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.

1. Capacitor
2. Inductor

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 IRFZ44N MOSFET.
• Arrange the Transistor at the working area.
• Go to Terminal Mode from the left most side bar 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.

2-bit Full Subtractor in Proteus ISIS

Hello mentees! Welcome on the behalf of The Engineering Projects. We are here with a new lesson about the Digital Logic Circuits. Logic Circuits work as heart in many electronic Circuits. The topic of today is Full Subtractor in Proteus and you will find the answers of the following questions:

1. What are 2 bit  Full Subtractors?
2. How can we design the Truth Table of 2 bit Full Subtractor?
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).

• This is the Full Subtractor circuit. Change the values of the Probes according to the Truth Table and record your observation.

  Consequently, Today we learned very useful circuit of Logic Design. We saw what are 2 bit  Full Subtractor, how can we design a  Truth Table of 2 bit Full Subtractor, what is the basic mechanism behind the working of 2 bit Full Subtractor and how can we perform a Practical implementation of 2 bit  Full Subtarctor using Proteus ISIS. In the next session, we'll learn how can we simulate a four bit Full Subtractor in Proteus ISIS and its basic concepts.

Half Subtractor in Proteus ISIS

Hey Pals! We hope you are doing Great. Today, we are going to design another application of DLD Logical Gates i.e. Half Subtractor. In our previous lectures, we covered Adders in detail, where we studied both Half Adders & Full Adders. Now its time to discuss its reciprocal i.e. Subtractors.

In this session, we'll seek the answers to the following topics:

1. What is Half Subtractor?
2. Working Principle of Half Subtractor.
3. Truth-table of Half Subtractor.
4. Simulation of Half Subtractor in Proteus using three Logic Gates.
5. Designing of Half Subtractor with NOR gate.

So, let's get started:

What is Subtractor?

The functionality of Subtractors is exactly the opposite of Adders(we discussed in previous lectures) and defined as:

• A Subtractor is a simple DLD Electronic circuit, designed using logic gates and is used to subtract binary numbers from one another.
• A DLD Subtrator generates two outputs(1-bit each) called Difference Bit and Borrow Bit.
• There are two types of Subtractors available:
• Half Subtractor. (We are discussing today)
  
• Full Subtractor. (We will discuss in the next lecture)

Now, let's have a look at the Half Subtractor:

Half Subtractor

DLD Half subtractors(same as Half Adders) are designed using logic gates and are quite simple in construction. We can define Half Subtractor as:

• "Half Subtractors are simple digital logical circuits, used to subtract two binary numbers from each other and generate two outputs called Difference Bit and Borrow Bit.
• The Half Subtractor takes two Inputs A and B and performs the subtraction operation i.e. A - B, where A is called Minuend Bit and B is called Subtrahend Bit.
  

Working Principle of Half Subtractor

The Half Subtractor has a boolean circuit. It means it works only with the two digits i.e, 0 and 1. The 0 describes the LOW bit and vise versa. It take two bits through the input Terminals and calculate the whole system then shows us the result at the Output Terminals.

Difference in Half Subtractor

The difference is obtained when we perform the minus operation with the second bit from the first bit. the calculator give us the output that is the remaining value of the 1st bit when we deduct the value of 2nd bit from it.

Borrow in Half Subtractor

In the case, when the second bit is higher then the 1st bit, the subtractor borrows a bit from the circuit. this is an essential operation because without this, subtraction can not be proceed further.

Half Subtractor Truth Table

In binary digit difference, the subtraction of 0 with 0 produces the difference 0 and the borrow 0. when the Value is change to A=0 and B=1 then the circuit borrows a bit and both the bits becomes 1 hence we get Difference=1 and borrow=1. When the inputs are A=1 and B=0 then we simply get the value Difference=1 and Borrow=0. At the same token, when A=1, B=1 then the result we get is Difference=0, Borrow=0. Using all these concepts we get the Truth Table as:

A	B	Difference	Borrow
0	0	0	0
0	1	1	1
1	0	1	0
1	1	0	0

In this tutorial we'll learn to design Half subtractor in two ways:

1. Half Subtractor using three Logic Gates.
2. Half Subtractor using only NAND Gate.

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

Half subtractors are used to limit the force of audio or Radio signals.

Half Subtractor Using three Logic Gates

In this type of formation we use three Logic Gate given below:

1. XOR Gate
2. NOT Gate
3. NAND Gate

When we look at the working of the Half Subtrator, we'll find that the working of the Difference mode of the Half Subtractor is same as the XOR Gate because we that that XOR Gate is the one that gives the output HIGH only when the inputs have different values from each other and vise versa. Just have a look at its Truth Table:

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

Therefore, we simple use the XOR Gat for the function of Difference. When we look at the Function of Difference. we use one AND Gate. A NOT Gate is attached with the one of the input of AND Gate. One may wonder, why we are using the two Gate when we can use the NAND Gate. but the point is, we just need the inverse condition of just one input. Therefore we use this arrangement.

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

• 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:

• 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.

2-to-1 Multiplexer using Logic Gates in Proteus ISIS

Hi Mentees! I welcome you on behalf of The Engineering Projects. In this section of this DLD Logic gates series, we are discussing different applications of logic gates. We have discussed DLD Adders and Subtractors in our previous lectures and now it's time to have a look at DLD Multiplexers.

1. What are Multiplexers?
2. What are the types of Multiplexers?
3. What are the two input Multiplexers?
4. How can we simulate the Circuit of 2 to 2 MUX in Proteus ISIS?
5. How can we use the 2 to 1 MUX as OR, AND and NOT gates?

What are Multiplexers?

When I heard the word Multiplexer, I thought that as Adder adds numbers, Subtractor subtracts numbers, similarly, the Multiplexer will multiply binary numbers but that's not the case. Multiplexer is defined as:

• A Multiplexer(also called MUX or MPX) is a simple digital electronic circuit, designed using DLD Logic Gates and is used to select a single input from multiple inputs provided to it.
• The input selection is controlled by a separate Input called Select Input(S).
• The selected Input is then forwarded to the Output Terminal.
• In a simple two Input(A₁, A₂) MUX,
1. If S = 0, the output(Y) will be A₁
2. If S = 1, the output(Y) will be A₂.

A Multiplexer is also called Data Selector, Universal Logic Selector, Many-to-one Logic converter and Parallel-to-Serial Convertor because it has the ability to select a single input from multiple inputs.

Let's understand the working principle of Multiplexer in detail:

Multiplexer Working Principle

Let's take the example of the simplest multiplexer i.e. 2-to-1 MUX. It has 2 normal inputs(A₁ , A₂ ) and 1 Select Input(S) and it generates single Output(Y). Here's the block diagram of a simple 2-to-1 Multiplexer:

As discussed above, the selection of inputs is controlled by the Select Pin(S). So, if S = 0, the output will be A₁ and if S = 1, the output will be A₂. The relation between Select Input and Output is shown in the below truth table:

Select Input(S)	Output(Y)
0	A1
1	A2

We can understand from the above truth table that we can control maximum 2 inputs from a single Select Input. So, in order to control more than 2 inputs, we need to increase the number of Select Inputs. For example, 2 Select Inputs can control a maximum of 4 Normal Inputs. So, the relation between Select and Normal Inputs can be described by the following formula:

Normal Inputs = 2ⁿ

where, n represents the Select Inputs.

So, if we have 5 Select Inputs, we can easily control 2⁵ = 32 Normal Inputs.

We have discussed its types in our Lecture. 2-to-1 Multiplexer As the name justifies, the 2 to 1 Multiplexer is the one where we have two inputs and only one output. Let's find what are 2:1 MUX. " The kind of Multiplexer or MUX that contains two inputs, one Selector and one Output is called 2-to-1 MUX or multiplexer. The inputs are usually named as D0 and D1, the selector is termed as S and the output is called Y." You can change the names of the inputs and output according to your choice.

Truth Table of 2-to-1 MUX

As we have discussed earlier, the inputs of Multiplexer depends upon a Selector S. therefore, when we design a Truth Table, we include a Selector also in it. While designing a 2-to-1 MUX, we follow the expression given below:

Y=D0S' + D1S

Considering the expression above we get the Truth Table of 2-to-1 Multiplexer as follow:

S	D0	D1	Y
0	0	0	0
0	0	1	0
0	1	0	1
0	1	1	0
1	0	0	0
1	0	1	1
1	1	0	1
1	1	1	1

  On the basis of above discussion, I am going to Produce a 2-into-1 MUX in Proteus ISIS.

Implementing 2-to-1 Multiplexer in Proteus ISIS

To Design a 2-to-1 Multiplexer, we need the following material:

Material Required

1. AND Gate
2. OR Gate
3. NOT Gate
4. Logic Toggle
5. LED
6. Ground Terminal

• Grab the required Material from the Pick Library one after the other by Pressing a "P" button present at the screen.
• Hit and hold the Name of the chosen Logic Gates one by one and arrange them at the screen according to the given image:

• Get Three Logic Toggles and set them just before the Logic Gates.
• Arrange an LED below the OR Gate's output.
• To have a ground Terminal, left click the mouse >Go to Place>Terminal>Ground.
• Join all the Components according to given image below:

• Pop the Play button just at the left corner of the screen and change the input.

NOTE: If your circuit shows the error of duplication, Simply change the names of gate by double clicking them and give them the desired name.

• Change the conditions of the System by changing the values of inputs and observe the output.

One can Use the 2-into-1 Multiplexer as the other Logic Gates. We discuss the usage of 2-into-1 MUX for the following Gates:

1. AND Gate
2. OR Gate
3. NOT Gate

Let's have a detailed way to use the 2-to-1 Multiplexer in the following way.

Implementing OR Gate through 2-to-1 Multiplexer in Proteus ISIS

The MUX Can easily be used to implement Basic Logic Gate. But before that Recall that what is an OR Gate.

"An OR Gate is a two input Logical Gate that give the output LOW only when both the outputs are LOW."

Procedure for the conversion of 2-to-1 Multiplexer into OR Gate

• Fix the value of D0 to 1 all the time.
• Change the Value of the S and D2 according to the Truth Table given below and match the result.

S	D0	D1	Y
0	0	0	0
0	0	1	1
1	0	0	1
1	0	1	1

Notice that the value of output is equals to the AND Gate.

Implementing AND Gate through 2-to-1 MUX in Proteus ISIS

Recall the definition of AND Gate:

" The AND Gate is the one that consist of two inputs and gives the input HIGH only when both the Inputs are HIGH."

Follow the simple steps to use 2-to 1 MUX as an AND Gate.

Steps to use 2-into-1 MUX as AND Gate

• Set the value of D0 as 1.
• Change the values of S and D0 according to table and record your observations.

 

S	D0	D1	Y
0	0	0	0
0	1	0	0
1	0	0	0
1	1	0	1

You can clearly see that the output is same as the AND Gate hence, you can use it as AND Gate.

NOT Gate through 2 to 1 MUX

Prior to start, Let's refresh the definition of NOT Gate in our minds:

"The NOT Gate is a 1 input invertor Logic Gate that gives the output 1 when input is zero and vice versa."

To use the 2 to 1 MUX as NOT Gate, just follow the steps:

• Set the D0 input as 0.
• Set D1 as 1.
• Change the value of S as 1 and zero  one after the other.
• You will Observe that when S=1 the output is 0 and vice versa.
• Hence this is our required result.

You can check our website for the XNOR, XOR and NOR Gate from 2 to 1 MUX in our Tutorials. Consequently, today we leaned interesting Circuits. We saw what are 2 to 1 Multiplexers. We made a circuit of the 2 to 1 MUX and from the circuit, we found how can we use them as OR, AND and NOT logic Gates along with the truth tables of each.

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.
