TRANSISTOR CONFIGURATION

There are three configuration of Bipolar Junction Transistor (BJT). According to the way input is fed and output is taken from the BJT.

TYPES OF CONFIGURATION

i. Common Base Configuration - CB Configuration
ii. Common Emitter Configuration - CE Configuration
iii. Common Collector Configuration - CC Configuration

COMMON BASE CONFIGURATION

In Common Base Configuration Output is taken across Collector and Base.

COMMON EMITTER CONFIGURATION

In Common Emitter Configuration Output is taken from Collector and Emitter.

COMMON COLLECTOR CONFIGURATION

This circuit is used for impedance matching as it has input impedance and low output impedance. It is a unity gain amplifier.
