Common Emitter BJT Amplifier in Proteus
Hi Learners, I hope you are doing good. This lesson is about implementation of one of the types of Amplifiers i.e,
Common Emitter BJT Amplifier. But, prior to this, we'll revise some basic concepts so that it will be easy for you to understand the roots of the Experiment.
We'll talk about:
- What are Common Emitter Bi-Junction Transistors.
- Concepts of Common Emitter Bi-Junction Transistors.
- Implementation of Common Emitter BJT Amplifiers in Proteus ISIS.
- Why we use Common Emitter BJT in Amplifiers.
What are Common Emitter Bi-Junction Transistors
There are three types of Configurations of a transistor named:
- Common Emitter Configuration
- Common Base Configuration
- Common Collector Configuration
We chose the Common Emitter Configuration due to its suitability (You will learn the reason).
We can
Define Basic Common Emitter BJT Amplifier as:
"A type of amplifier circuit made by a Bi-Polar junction Transistor that uses NPN BJT Transistor, inverts the voltage output wave at 180 degree and is the one from the three basic BJT amplifier Configuration."
Recall that
A Transistor is made by combining two diodes in required manner. Hence, It there are two types of Transistors:
- NPN configuration.
- PNP Configuration.
Here N is the symbol for Negative doping and P is the symbol for positive doping.
Concepts of Common Emitter Bi-Junction Transistors
At this instance We'll look at some basic concepts, on the basis of which we chose these Components along with the values of Components of amplifier.
Current gain:
In BJT Amplifiers, current gain is the ratio of change in collector current to the change in the current of base.
mathematically, Current Gain= Change in collector current/Change in Base Current
ß=?Ic/?Ib
At the same token,
Voltage Gain:
The Voltage Gain of an amplifier is the product two Quantities. One is the ratio of output resistance of the collector to the input resistor of the base, and the other is the current gain.
Voltage Gain=ß(Rc/Rb)
During the Practical work we take AC output voltage from collector with respect to emitter and the Output of Amplifier is taken from Collector. On the other hand, the input is given to the base terminal.
It is obvious to notice that the emitter is Common to Base and Collector. It consist of Voltage divider biasing, hence one of the basic part of circuit is consist of two resistors so that their mid-point is used for supply Base Bias voltage. One more importance point to remember is gain is different from one transistor to the other.
Biasing:
Biasing is a technique to add the Battery in a circuit. It is important in Electronic devices because it establishes the correct operating point of the Transistor amplifier when it is ready to receive the signal from input and hence the plays an important role in reducing the distortion in the output.
If we look at the characteristics then we come to know that Common Emitter BJT Amplifiers has high voltage gain, the current gain is medium and the circuit has a high power gain.
Implementation of Common Emitter BJT Amplifiers in Proteus ISIS
For the practical verification of the circuit It is always Advisable to Perform it at any simulation software. Hence open Your Proteus ISIS.
Components Required:
- NPN transistor (2N171) .
- Vsine
- Capacitor
- Resistor
- DC Power source
- ground Terminal
- Oscilloscope
Procedure:
- Choose 1st four Components from the Pick Library "P" one by one by writing their name in it.
- Collect the DC power supply from "Generator mood" present on the left most tab.
- To get the Ground terminal, left Click on the working screen and go to Place>Terminal>Ground and fix it on the screen.
- Oscilloscope is present in the "Virtual Instrument Mood" on the same tab.
- Once you have chosen all the required Device then set them one by one on the Working area according to the Picture given below and connect them with the help of wires.
- At the Instance we will change the values of some devices So I have made a table for this:
-
| Components |
Values |
| Resistor R1 |
60ohm |
| Resistor R2 |
500ohm |
| Resistor R3 |
1000ohm |
| Resistor R4 |
2000ohm |
| Resistor R5 |
100ohm |
| Oscilloscope |
A=20V, B=2V |
| Vsine |
Frequency=1000Hz, Amplitude=110V |
| DC source |
10V |
After substituting the value we get the prepared circuit for the amplifier as:
It seems that all the things are ready. Once you play the simulation then you can change its values and You will acquire the following output.
- Select the Current probe from the left most bar and connect them in the circuit one with the Base wire and the other with the collector.
One can find the current gain by simply putting the values in the formulas given in the concepts portion.
here,
Current gain=6.2*10-12/6.1
=1.01*10-9
as it is a ratio, hence has no unit.
At the same token,
Voltage gain=1.01*10-9*(500/2000)
=2.5*10-10
NOTE: The Gain is vary from transistor to transistor and the temperature is also an important feature. Therefore, the gain is always unpredictable.
- We got the required output in the Proteus ISIS as required.
let's find out why we used this for our experiment.
Why we use BJT in Amplifiers
Common Emitter BJT Amplifiers are important in the World of Electronics. One can get the idea of their influence by the following points:
- These Amplifiers are used in low frequency voltage amplifier.
- The are useful because of their high power gain with medium voltage and current gain hence they are cheap.
- The output impedance is high.
- It has inverting effect so can be used in the different appliances for different purposes.
In today's tutorial, We learnt what is Common Emitter BJT amplifiers, some basic concepts along with the simulation in the Proteus ISIS. We also saw why these Amplifiers are used in the real life.
The circuit and the output may vary for other circuits but don't worry about that because it is a very sensitive circuit.

Common Base BJT Amplifier in Proteus
Hi mentees, Welcome to
The Engineering Projects. If you are seeking for the Practical Implementation of
Common Base bipolar Junction Transistor amplifier then you clicked at the best website because we'll cover the basic concepts and the procedure step by step.
So, Lets start the learning.
What is Common Base BJT Amplifier?
The precise definition of the Common Base BJT Amplifier is:
"The type of Bipolar Junction Transistor Amplifiers in which Base is Common to both emitter and Collector and Current gain is taken from the Base is called Common Base bipolar Junction Transistor Amplifiers."
Recall that a transistor has three regions i.e, Base, Collector and Emitter. Hence we design our Circuit in such a way that we get the output of current from the base and get the best current gain.
Basic Concepts:
Some Important Concepts should be kept in mind so that it will become easy and interesting to Design the Circuit.
Current gain:
" The Current gain of Common base Amplifier is equal to the ratio of Current in the Collector to the Current in the Base provided by the constant voltage of base to collector."
Mathematically,
Current gain=Collector Current/Base Current
ß=Ic/Ib
Voltage Gain:
"T
he Voltage gain of the Common Base amplifier is obtain when we divide the Voltage of Collector to the voltage of emitter."
mathematically,
Voltage Gain=Voltage of Collector/Voltage of Emitter
Av=Vc/Ve
Type of Transistor:
In the Common Base amplifiers, we use the NPN transistor because in this way we get the require output more easily. In NPN transistors, majority is the electrons. The mobility of electrons is better than holes (in PNP Transistors) so they are faster.
Biasing:
Biasing is a technique to add the Battery in a circuit. It is important in Electronic devices because it establishes the correct operating point of the Transistor amplifier when it is ready to receive the signal from input and hence the plays an important role in reducing the distortion in the output.
Common base MUST correctly Biased so that the base-emitter junction will remain forward Bias.
Now, Let's move towards the practical implementation.
Implementing Common Base BJT Amplifier in Proteus ISIS
To Perform the experiment. we need the Proteus ISIS then follow the steps:
Material Require:
- Transistor (2N1711)
- Capacitor
- Alternating Current Source (Vsine)
- Resistor
- Oscilloscope
- Ground.
- Open Your Proteus software in the PC.
- Seek the Pick Library "P" button and write the name of 1st four Components one by one and select them.
- Place the current components on the working area.
- Acquire the Oscilloscope from the "Virtual Instruments mode" from the left most area and fix it just above the circuit.
- You can obtain the Ground Terminal by left click on the screen>Place>Terminal>Ground or just search it in the "Terminal mode".
- Connect all the Components through wires. The circuit looks like the image given below:
- At this instance , Change the name and values of resistors one by one by double clicking them. In this way, the circuit will work Perfectly.
- I labelled all the Resistors with different names and changed the values according to the need.
- At the same token, the name of Capacitor, battery cells and their values are also changed according to the table given below:
| Components |
Values |
| Resistor R1 |
400ohm |
| Resistor R2 |
30ohm |
| Resistor R3 |
100ohm |
| Resistor R4 |
200ohm |
| BAT |
50 |
| BAT 1 |
200 |
| CIN |
2mF |
| COUT |
60uF |
| Oscilloscope |
Channel A=20V, Channel B=20V, time=0.5m-1 |
| VSine |
Amplitude 220V, Frequency=1000 |
- Set all the values according to table.
- Once the values are selected (except Oscilloscope) just Pop the Play button.
- You can see an Oscilloscope screen showing the waves.
- Turn of the Channel C,D to avoid distraction.
- Set the values of Oscilloscope by matching with the table.
- You will get the output just like shown in the following image:
The Yellow wave (channel A) indicates the input wave were as the Blue Wave (Channel B) indicates the output ( Amplified) wave.
Hence by If we choose the Components and there value carefully, we get the best output.
Lets Calculate the Current gain then Voltage Gain.
I am using the previously Described precepts to calculate the Quantities:
- Connect the DC Ammeter from the "Generation Mode" and Connect one with the Base of transistor and one with the Collector.
- When we play the Simulation then we get the following Output:
Applying the values into the formula we get,
ß =-1.43/-0.07
=20.4
As it's a ratio so it doesn't have any unit.
Moving towards the Voltage Gain,
- Take the "DC Voltmeter" from the same Portion and connect one Voltmeter with CIN capacitor and one with the COUT Capacitor. Note than the Voltmeter is always Connected in parallel to the required Components.
At the moment, When we start the simulation, we get the following output:
Applying these Values for Av,
Av=53.1/3.75
=14.16
So that the required Quantities are obtained.
Characteristics of Common Base BJT Amplifiers:
- It has High Voltage Gain.
- The Current Gain of Common Base BJT Amplifiers is Medium.
- We get High power Gain in this type of Amplifier.
- Common Base Amplifier does not have any reversal effect between input and output waves.
- The Input and Output resistance of the Common Base Amplifier is Medium.

- It is useful due to its high power gain.
- The output Impedance is High for Common Base Bipolar Junction Transistor Amplifiers.
- The Output Impedance is high.

Interfacing Flame Sensor with Arduino
Hello everyone! I hope you all will be fine and having fun. Today I am going to tell you that how can you make a simple program for
Interfacing Flame Sensor with Arduino. Flame sensor is used in offices, home and at different places to detect the fire. First of all I would like to tell you about the working principle of the flame sensor. Flame sensor is a device designed for the detection of the fire and to respond it. They are usually designed for the detection of most frequently used industrial fuel e.g. diesel, gasoline, karosene, ethylene, hydrogen etc. They are designed in way to distinguish between the radiations from the sunlight and the actual flames.
There different types of flame sensors e.g. Ultraviolet (UV) detectors, Infrared (IR) flame detectors, UV/IR detectors, IR/IR flame detectors, closed circuit video cameras. The purpose of these all flame detectors/sensors is almost similar i.e. to detect the fire and responding quickly to it. The flame sensors have a wide range of applications in our daily life e.g. fume cupboards, felt manufacture, nuclear industry, pharmaceutical industries, printing, spray booths, generator, storage tanks, industrial heating and drying systems etc.
