Common Source MOSFET Amplifier Calculator

Calculate the small-signal voltage gain of a common source MOSFET amplifier.

Step 1: Enter Circuit Parameters

Transconductance, \(g_m\) (S)

Example: 0.002 S (2 mS)

Drain Resistor, \(R_D\) (\(\Omega\))

Example: 10000 \(\Omega\) (10 kΩ)

Source Resistor, \(R_S\) (\(\Omega\))

Enter 0 if a bypass capacitor is used.
