Common source


A common-source amplifier is one of the common configurations of FET electronic amplifier.

Characteristics

Inherent voltage gain:

With CS:
- gm(RD | | Rload)
Without CS:
-g_m (R_D || R_{load}) \over 1 + g_m R_S

Input resistance:

R1 | | R2

Current gain:

A_{vm} {r_{in} \over R_{load}}

Output resistance:

RD
