SHORT NOTES

ALL ABOUT 3 TRANSISTOR
CONFIGURATION

1=COMMON BASE(CB)

Ri=Lowest                  Ro=Highest  

Ai=Lowest                  Av=Highest          Ap=Moderate 

Phase shift=Zero

Application=As a non inverting voltage amp

                      As a impedance matching(lowest
to highest)

2=COMMON EMITTER(CE)

Ri=Ro=Moderate    

 Ai=Av=Moderate         Ap=Highest

Phase shift=180 

 Application=Mostly use(95%)

3=COMMON COLLECTOR(CC)

Ri=Highest      Ro=Lowest   

Ai=Highest  Av=Lowest     Ap=Lowest

Phase shift=zero

Application=As a Emitter follower,buffer amp,impedance matching(highest
to lowest),audio frequency power amp

NOTE-Ri=Input resistance      Ro= Output resistance

Ai=Current gain           Av=Voltage gain                  Ap=Power gain
