What is Bistable Multivibrator

Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at What is Bistable Multivibrator and how it can be used in different circuits. In this type of multivibrator, the circuitry can operate in any state according to a signal provided at its input while it does not happen in a monostable multivibrator. This arrangement is also defined as a flip flop because flip flop also operates at more than one condition. It also has the ability to store a single bit of information so it is mostly used in logic circuits and in computer data storage part.

This vibrator like other vibrators is used for the production of square waves with providing some delay. These circuits are constructed with numerous kinds of semiconductor components. The most used semiconductor device circuits are operational amplifiers. In today's post, we will have a look at its working, construction, applications and different parameters related to it. So let's get started with What is Bistable Multivibrator.

What is Bistable Multivibrator

• Bistable Multivibrator has 2 operating conditions so it is called bistable, it is also known as a 2-shot multivibrator.
• Due to working at two different modes it needs 2 input signal for shifting from one operating mode to others.
• When first input signal is provided it shifts its operation to second state when second signal provided it come back to previous state.

• Its another name is flip-flop multivibrator because like flip flops its changes its operation state and regain it after some interval.
• In the given figure, its structure is shown that consists of 2 NPN transistors that is denoted as Q1 and Q2.
• At both of these transistors collector 2 loads resistors, RL1 and RL2 are attached.
• The output terminal of the first transistor is connected with the input of the second transistor through resistor R1 and output of the second transistor is provided at input of first transistor through the resistor R2.
• Both of the resistance R1 and R2 are connected with a capacitor in parallel. The purpose of these two capacitors is to enhance the switching feature of circuitry so they are also known as commutating capacitors.

Bistable Multivibrator Working

• Now we discuss the working of this vibrator, for this, we discuss the circuitry that given below figure its construction and components we already discuss so now we the working of these components.
• When input power is provided to the input terminals of first transistor-transistor starts its operation due to a difference in its feature than the other transistor.
• When it first transistor starts its operation it goes into saturation state. Due to this value of voltage decreases at the collector terminals.
• As we know the collector of Q1 is connected with the base terminal of a second transistor due to this it goes into the cutt-off region.
• Then the voltage at the collector increases to Vcc, this increment in voltage causes to further saturate the first transistor as this voltage is connected with base of Q1 through the resistance R2.

• It is the first operating condition of bistable multivibrator in which first transistor Q1 is in working state while Q2 is off.
• This first condition continuous to that point we do not provide the negative signal to first transistor Q1 and positive polarity to transistor Q2.
• Now if we provide the positive polarity signal to the second transistor Q2 by the capacitor C2 connected with it.
• This Process will change the second transistor Q2 from saturation mode to cut-off mode, and voltage will decrease at a collector of Q2.
• As the collector of transistor Q2 is attached with the base of transistor Q1 with the decrement in the voltage at the collector of causes to decrease voltage at transistor Q1 base.
• This cause to the second transistor obtain saturation state and it is the second operation mode of this module in which the first transistor is off and second is in an operating state.

Bistable Multivibrator Waveform

• The output waveform generated by the has smaller wavelength or larger according to circuit requirement in rectangle shape.
• The first end of the rectangle waveform depends on the first input signal and vary according to it and second relies on the second input signal, the resultant waveform is drawn in a given figure.
• Switching variation among these 2 modes can create bistable circuitry but in some cases it is possible.

TTL Bistable Multivibrators

• As we above constructed this circuitry by using 2 different transistors now we use integrated circuits for the production this vibrator.
• The given circuitry explains the circuitry of a bistable vibrator having two NAND gates.

• This kind of circuits arrangments is known as the Bistable Flip-Flop, in this circuitry, there is a switch that is single pole through a switch (it is such switch that takes one input and can regulate 2 different output). This switch provides logic one and zero to this circuitry.

Application of Bistable Multivibrator

• It used in different storage devices and for counting of binary numbers.
• For frequency division in different circuits.
• It used for the production of different clock pulses.
• It used for different relay controller.
• It used in the different circuit as a toggle switch.

What is Monostable Multivibrator

Hello fellows, I hope you all are doing great. In today’s tutorial, we will have a look at What is Monostable Multivibrator. It is a simple electronic circuit, used to produce a pulse at its output also known as one shot. It generates output pulses according to corresponding circuitry requirements. Its main feature is that after the generation of the output pulse, it regains its stable state and does not produce any further output pulse till not triggers again.

This circuitry can be considered as a biased form of multivibrator (such circuitry that is used for implementation of 2-state modules like timers) that is (on) operating in the starting condition till the triggered point and then becomes unstable on its own. In today's post, we will have a look at its circuitry, construction, working and related parameters. So let's get started with What is Monostable Multivibrator.

What is Monostable Multivibrator

• Monostable Multivibrator is used for the generation of a square waveform in electronic circuitry.
  
• This wave generator belongs to a group of wave generators known as Relaxation Oscillators.
• It has a simple circuit where 2 switching circuits are designed using transistors(acting as a switch).
• The transistors are assembled in a way that the output of one transistor is the input of the second transistor.
• This circuitry also consists of a capacitor and resistor network to create feed-back tank circuitry.
• There are 2 different working conditions in any multivibrator circuit but monostable has only one 'on' state.
• This vibration generator comes back to its original condition after a set time of resistor-capacitor circuitry.

 

Construction of Monostable Multivibrator

• In its construction, 2 transistors are connected in such a configuration that both of these operate as input and output providers to each other.
• The collector (c) of the first transistor is linked with the base (b) of the second through a capacitor denoted as C1 and base terminal of first transistor that denoted as Q1 is attached with a collector of second transistor by the resistance R2 and capacitor.
• A direct current source is connected with base (b) point of first transistor by the resistance R3. The input pulse is provided to base (b) of first transistor with the capacitor denoted as C2.
• In figure resistance, (RL1) and resistance (RL2) is the load connected with these two transistors.
• When any transistor goes into stable state, then at input pulse is provided to vary its condition. With variation in condition, transistor stays in this condition for time interval set by the resistance-capacitor time constant then get the earlier condition.

Monostable Multivibrator Waveform

• This wave generator produces a waveform of rectangle shape having low and higher amplitude, the first end of this wave generates with the input trigger signal and the second end generates resistor-capacitor time constant.
• This resistance-capacitor time constant changes its value to generates large no of pulses that have a specific time interval between them by following the trigger signal provided at input. This assembly is shown in a given figure.
• The resistor-capacitor time of this vibrator can be change by changing the capacitance of capacitor or resistance value of both.
• The circuits also have the ability to do increment in the dimensions of a wave as the frequency of output wave remains similar to input signal the difference between them is the width of the waves.

TTL Monostable Multivibrators

• Above we discussed that this vibration generator can be constructed from individual elements like a transistor, but it can also be manufactured by different ICs.
• This given circuitry explains how the using only two NOR gates we can construct monostable vibrator.
• As we are familiar with the operation of NOR gate that its input is low than output will be high and if input is high then the output will be low (0).
• So at the start, the input is 0 then the output will be higher mean '1'.
• The resistance Rt linked with the input is also at a high level '1' it means that the quantity of charge at the plates of capacitor is similar.
• The voltage (V1)  is equivalent to this voltage so the output of NOR is at level 0.

• If the positive signal is provided to the input at a time (t=0) then the output of NOR gate will be '0' due to this the capacitor will get a discharge.
• Due to the discharging of the capacitor, the input of second NOR gate is '0'  that converts into high output '1'. This condition is called second condition of circuitry, in which output voltage is equivalent to (+Vcc).
• This condition continuous on second NOR gate until the capacitor does not get charged again.

Applications of Monostable Multivibrator

• These are some important applications of Monostable Multivibrator that are described here.
• Due to time delay capability, it is mostly used in different timer circuits.
• It also used in different storage circuits.
• It also used to provide input to other pluse generator circuits.
• It also has ability to reproduce damage pulses again.

Advantage of Monostable Multivibrator

• These are some benefits of this pulse generator over other pulse generation modules.
• It needs only one single pulse to start its operation there is no need of extra pulse for its operation.
• Its construction is very simple and can be constructed easily.
• Due to simple construction its price is also less.

So, this is the complete article on  Monostable Multivibrator if you have any questions about it ask in the comments. I will solve your problems. Thanks for reading.

Introduction to Darlington Transistor

Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at detailed Introduction to Darlington Transistor. It was named "Darlington" as its inventor's name was Sidney Darlington, who was an electrical engineer and belonged to the United States of America. Such a circuit configuration that consists of 2 PNP or NPN transistor makes Darlington configurations. This transistor configuration is used for amplification and switching circuits. The signal amplified by the first transistor also amplified by the second transistor & due to this two-time amplifications, this arrangement provides a high gain output signal. This transistor operation is similar to normal single transistor that has a base, emitter and collector. Its current gain value is almost one thousand. In today's post, we will have a look at its working, structure, applications and other related factors. So let's get started with Introduction to Darlington Transistor.

Introduction to Darlington Transistor

• Darlington transistor ( also known as Darlington pair) comprises of 2 bipolar junction transistors, connected in such a way that they behave like a single transistor.
• This transistor converts low base current to high output current (collector current).
• Its construction is such that emitter terminal (E) of the first transistor that is input connected with the second transistor base (B) terminal and collector (C) terminals of both transistors are linked together with one another by a wire.

• In this configuration current amplified by the first transistor further amplified by the second transistor and its give high gain output.
• There are two kinds of power dissipation occurs in this transistor first is maximum Collector-emitter (CE) and second is direct current gain. The value for maximum Collector-emitter (CE) is thirty volts, sixty volts, and eighty volts.
• As the gain value of this transistor is one thousand so less value of IB needs to using it in different amplification and switching circuits.
• Its most important factor is that its impedance at the input is high that cause to decrement at the output due to this we get a high-value signal.

Darlington Transistor Structure

• The physical construction of the Darlington pair is drawn in given below figure. In this figure, we are working on NPN transistors for construction of the required circuitry.

• You can see that collector of these 2 transistors are linked with each other and emitter terminal of transistor denoted as TR1 connected with the base (B) of the second transistor to provides the current at base.

• This circuitry gets ß multiplication due to Ib and Ic, in this case, the value ß  is larger than one, its mathematical form is.

IC= (IC1+IC2) IC= (ß1) . (Ib)+ (ß2). (Ib2)-----(1)

• While the value of Ib of TR1 is equivalent to the emitter current of it and the emitter of the first transistor is linked with the base of second transistor TR2.

(Ib2) = (Ie1) =(Ic1) + Ib) =(ß1).(Ib) +(Ib) = (IB).(ß1 + 1)

• If we put the value of Ib2 in equation (1) then we have.

Ic=(ß1). (Ib)+ ß2.Ib(ß1+1) Ic= (ß1).(Ib)+ (ß2).(Ib)(ß1) + (ß2).(Ib) Ic= (ß1+(ß2.ß1)+ ß2).Ib

• In these equations the ß1 is the gain of first transistor and ß2 is the gain of second transistor.

Sziklai Transistor Pair

• This type of transistor configuration was first time created by George Sziklai who belongs to Hungry, its name is due to this scientist who created it. It comprises of NPN and PNP transistor that are connected in given below configuration.

• The arrangement of NPN and PNP transistors in circuitry has a benefit that this Sziklai combination does a similar function like normal Darlington transistor, but it needs 0.6 volts extra for its starting operation.
• The circuitry of this transistor combination is shown in the given above figure.
• You can see that the voltage drop of this configuration across base and emitter terminals is equivalent to the voltage drop across a single transistor.
• The operation of Sziklai is slower than the Darlington pair transistor. These transistor pair are normally used for pull-push arrangements and different sound amplifier circuits.
• But common thing in these two transistor arrangments is that they use in NPN and PNP transistor for their construction.

Darlington Transistor Example

• For a practical understanding of the Darlington pair transistor, we solve an example.
• Let's suppose that we have a load that consuming the power of sixty watts is connected with fifteen volts supply and 2 NPN transistor in Darlington pair arrangements.
• The gain value of the first transistor is thirty and another transistor gain value is ninety-five. So by using these given parameters, we calculate the value of Ib to operate the load.

• When the output load starts to operate then collector current flows this collector current is equal to the current consumed by the load.

IL= Ic

• As we know that P=VI. So,

Ic= P/I

=60/15= 4 amperes

• As above we discussed that the value of ß is 30 and for second is 95, so the value of Ib can be calculated by this equation.

Ic =[ß1 +(ß2 x ß1)+ ß2] x Ib

Ib=(Ic)/[ß1 +(ß2 x ß1)+ ß2]

Ib=4/[30 +(95 x 30)+ 95]

Ib=4/2975

Ib=1.3mA

• From this, we can conclude that if we provide 1.3 milliamperes to the first transistor, load start its operation when we disconnect current load will off.

Advantages of Darlington Transistor

• These are some important benefits of this transistor arrangement that are described here with detailed.
• It gains value is very high almost one thousand and sometimes greater than it, so a small value of Ib will be amplified to the larger output current.
• Its resistance at the input is very very high that decreases the resistance value at its output.
•  As this circuit is very easy to construct so it is easily available in numerous structure in a single casing.

Disadvantages of Darlington Transistor

• Where it has some benefits there it also has some drawbacks that are described here.
• Its main disadvantage is that its saturation voltage is higher than the normal transistor.
• The value of saturation voltage is 0.65 volts for Darlington pair while in case of a transistor is 0.1 to 0.2 volts.
• Another problem is that its switch time increases if the first transistor does not send Ib to the second current within the required time. That makes its operation slow.
• In the presence of large frequency signal, it shows the high phase shift that is low in a single transistor, due to this it losses stability when negative feedback is provided to this circuitry.

That is the detailed article on the Darlington Transistor I have mentioned every aspect related to this transistor. If you have any issue ask in comments.Thanks for reading.

Smart Energy Engineering Drives Manufacturing Growth

Hi Friends! Hope you're well today. I welcome you on board. In this post today, I'll walk you through how smart energy engineering drives manufacturing growth. Human life on earth has never seen more development it has experienced in the past 100-years. Nowadays, manufacturing is based on smart tech-oriented engineering. This guarantees quality productions in the minimum time possible. According to the British newspaper Yorkshire Post, a new $252m Siemens manufacturing site in the UK is a poster-boy for this new trend of super high tech combined with manufacturing. Innovative digital engineering solutions play a key role in upscaling these companies with modern-day technology that gets rid of older, classic manufacturing techniques and provides a cleaner, safer, and faster way of manufacturing goods.

Futuristic ovens

Needless to say, industrial ovens are necessary for manufacturing purposes. The creation of industrial ovens scalable to fit the industry's precise demands are prerequisites for the required airflow for the job, the type of energy used, and the lifespan of production. You know it already if industrial machinery misses the mark and fails to meet the industry standards, this can terribly impact the overall production. The reason, you need advanced machinery equipped with cutting-edge technology to grow your revenue skyrocket. These ovens are part and parcel of manufacturing with outstanding results in both the simple drying process and hydrogen de-embrittlement. Soon, innovators are expecting to use solar energy to power such ovens. In November 2019, CNN reported on a breakthrough made by Bill Gates’ secretive energy start-up that it had managed to concentrate heat in one area. Scaling down of this technology could be a further boon to an industry that helps tackle energy concerns with full control.

Further energy storage

These systems may well be expensive, but new technology is proving fruitful for energy storage and movement. And based on result-driven and swift processes, you will surely admit, they totally worth it. According to The Independent, breakthroughs in battery manufacturing have made Li-ion batteries 90% cheaper in material costs – also a sustainability saving – and have made manufacturing far easier. This will have far-reaching implications for manufacturing businesses across numerous sectors, particularly the car industry including EV, hybrid, or CEV. Furthermore, by using a chemical resin instead of heavy metals, these batteries degrade slower and have a lessened environmental impact, leaving your atmosphere with no toxic gases. They could lead to a serious overhaul in how manufacturing is done from the energy management perspective.

A reduction in waste

Energy-saving at the front-end is great and it is equally important in tuning energy usage to encompass largely green fuels. There remains, however, the question of waste. According to industry consultants Enel, significant energy is lost in the processing of manufacturer lines that are often uncovered at a later date in efficiency programs. However, they will go missing for years in the meanwhile, and this necessitates savings to be made elsewhere. One such way is through turning waste once again into energy. It comes with two benefits; first, if energy is wasted it’s less impactful as there is a zero-sum game; second, it creates efficiencies for manufacturers that can help against the impact of hidden problems in their assembly line. Finding a way to harness waste and turn it into energy should be a primary concern for manufacturers, both in environmental and cost-saving ways, and there are methods out there that may prove helpful for energy conservation.

The Icelandic method

Iceland is renowned for its use of geothermal energy which, according to IRENA, produces just 3% of the emissions that equivalent energy-producing operations will create. Despite this, the island nation is not contented on its laurels and manufacturers, the reason they have come together to look at turning waste into energy. The result is a program of gasification run by the University of Iceland. The main aim is to look at waste from all areas of manufacturing and day-to-day life and turn the waste materials and energy (in the form of heat, light, and emissions) back into useful energy by capturing and re-introducing materials to the manufacturing process. While still a relatively ‘dirty’ process – these are, ultimately, fossil fuels and bio-energy – this can represent a ‘closed-loop’ on emissions for manufacturing businesses and the opportunity to make the most out of every single piece of work. In turn, this reduces the amount of wastage at every stage of production.

Moving to clean processes

Long-term businesses must look to move away from all dirty and inefficient fuels and turn toward more clean and effective alternatives. Much of this is being completed already by private energy firms. Forbes estimates that fossil fuel usage will reduce from 82% of current global consumption to 60% by 2040 and this rate will be much higher in developed countries compared to third-world countries. In the USA, regardless of political pressure, energy companies are investing heavily in renewables that are becoming a part of the energy grid. While effective work can be done on the factory floor to clean energy compliance, regulators are doing great work to bridge that gap and ensure a much cleaner environment.

Future: the hydrogen solution

Hydrogen is a volatile energy that carries plenty of risk in the manufacturing process. According to engineering mag The Engineer, it could be the next big breakthrough – and one that is more palatable to the public than controversial nuclear energy. Scale-able hydrogen operations that pluck energy out of the air are springing up across the world and are, crucially, scale-able – they could find their way onto the site of manufacturing premises.   Hydrogen is, no doubt, inherently dangerous and carries a lot of risks, however with the help of advanced technology its impact can be reduced; for instance, some units have safety systems that rapidly turn Hydrogen stocks into oxygen if a dangerous situation arises. Clean and safe energy with the tendency of conversion is arguably the future fuel for manufacturing. This also leads to a clean and secure environment. Clean energy with large-scale manufacturing is the dream for both businesses and consumers. If engineers continue to focus on clean energy solutions for manufacturing, it will benefit both industry and environment that guarantees maximum production requiring less labor force.

Arduino Mega 1280 Library for Proteus

Hi Guys! Hope you’re well today. Thank you for viewing this read. In this post today, I’ll walk you through the Arduino Mega 1280 Library for Proteus. You may already be familiar with Arduino Boards, in case you don’t, they are the open-source easy to use hardware and software platform used in modern electronic projects. These boards receive inputs and convert them into outputs to activate motors, LEDs, electrical circuits, robots, and embedded systems. They are mainly designed for newbies and non-tech geeks who hesitate to construct the electrical circuits from the get-go and hate diving into the nitty-gritty of architecting electrical wires accurately to fashion electrical circuits. Arduino boards come with both ready-made electronic kit and software program IDE (Integrated Development Environment) that runs on the computer. You only worry about the running code on your system, without involving into the hassle of organizing and connecting everything perfectly on your electrical circuit. We’ve already discussed the Arduino Mega 2560 Library for Proteus. Both Mega 2560 and Mega 1280 are almost similar in working and execution with a slight difference in flash memory and microcontrollers incorporated on the boards. Arduino Mega 2560 carries Atmega 2560 microcontroller with flash memory 256kb while Arduino Mega 1280 carries Atmega 1280 with flash memory 128kb. These boards can be powered by both USB cable and external power source where AC-to-DC adaptor or battery is used to power them externally. Our team is designing and adding these new libraries in the proteus library database to help students better understand the working of Arduino boards in proteus workspace.
