In this video, we discuss the Common Base (CB) Configuration of Bipolar Junction Transistor (BJT) in a simple and easy-to-understand manner.
This lecture explains the working principle of common base configuration, including circuit operation, current flow in NPN and PNP transistors, biasing conditions, and current relationships.
The concepts of input and output characteristics, current gain (α), input impedance, output impedance, voltage gain, Early effect, and punch through are clearly covered.
We also discuss why the common base amplifier has low input impedance and high output impedance, and why its current gain is less than unity, along with its practical applications and limitations.
📌 Topics Covered:
Common Base Configuration basics
CB amplifier working
NPN & PNP transistor operation
Input & output characteristics
Current gain (α)
Advantages, disadvantages & applications
