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.
