In the common collector configuration the signal is applied to the base and taken from the emitter. The collector is the element common to input and output circuits. Figure shows this configuration. The next formulas are used to calculate the hybrids parameters.

 

 


 

 

 

Formulas 1

Common collector:

 

V1 = Vbc

I1 = Ib

V2 = Vce

 

Where:

Vcb is the voltage between base and collector in volts (V)

Ib is the current flowing through the base in amperes (A)

Vce is the voltage between collector and emitter in volts (V)

Ie is the current flowing through the emitter in amperes (A)
