BJT : Common Base Configuration Explained

In this video, the common base configuration of the BJT has been explained.

By watching this video, you will learn the following topics:

0:00 Introduction

1:11 What is Common Base Configuration

2:55 Input Characteristics of the Common Base Configuration

5:45 Output Characteristics of the Common Base Configuration

6:33 Three Different regions of operation (Active, Saturation, and Cut-off)

10:52 Signal Amplification in CB Configuration

Common Base Configuration of BJT:

In the case of the Common Base (CB)configuration, the base terminal is common between the input and the output side.

In this configuration, the input is applied between the emitter and the base terminal while the output is measured between the base and the collector terminal.

These are the few properties of the CB configuration:
Low input impedance
High Output Impedance
Low current gain
High Voltage Gain
Low Power Gain

In this video, the input and the output characteristics of the common base configuration have been explained with the graphs and at the end how the signal is amplified in the CB configuration has been explained.

This video will be helpful to everyone in understanding the common base configuration of the BJT.

Some the most valuable 15 minutes of my life

[alexstone]

Your videos are such treasure for people wanting to learn electronics, thank you!

[dindor]

Transfer + Resistor = Transistor. This was my wow moment!

[umareddy]

I was sufferd from this concept in my yesterday class .
It is very helpful for me
Thank you bro

[GAURAVKUMAR-veec]

This will help me to get good marks in my sem exam...thanks sir😍

[cjemon]

Wow this video waited 3 years for me....
I'm so grateful, thank you sir😍

[nassional]

You are like a gift to people like us who want to learn something. It was more productive than my engineering education. Thank you.

[manjitroy]

all videos are just awesome unbelievable that that area vailiable in utube thank god i got it some how . thanks a lot to u carrry one for other topic also .

[tanviranjum]

Best class. I have ever done!
Hat's off🌻, Sir..
From Bangladesh... 🙂

I might've missed it, but introducing the shottkey equation would help. That way, base emitter resistance can be introduced without hindrance, not to mention even that output curve.

[eearkadeepmukherjee]

May god bless you sir, you are like a hero to us

[moumitade]

Sir a 100 thanks for clearing the basics of transistor

[SrinivasMarpina]

Neso academy and this channel are surviving my life

[AkpogheneOnyx-owin]

If my lecturer explains like this we wont sleep in class

[gowrishiridi]

Valuable information thank you so much you made it this topic easy and now i also able to explain this topic to others once again thanking you sir thank you so much

[durgeshsavale]

Excellent teaching than our polytechnic college faculty

[life_leezybeezy]

Your knowledge is just brilliant. Can you just clear me that why did you switch to PNP while explaining the voltage amplification? At 10:52.

[ravik-kant]

Your video is only 15 minutes but I completed it in around 1.5 hours...❤

[sayansaha]

Sir I found out one mistake in your video as per my knowledge. In your video you told that the output characteristics curve for common base configuration is linear but I verified from Sedra Smith that the curve is not the liner it has a small positive slope which indicates that the Ic depends upon Vcb in the active mode.
