Common Gate Amplifier Gain. To derive the voltage gain let s draw the small signal equivalent circuit. Look out of the 3 mosfet terminals and make.
The bulk is not tied to the source ibias assume an ac short s vbias. As usual let s express and to find the voltage gain with because the gate is grounded. The analogous bipolar junction transistor circuit is the common base amplifier.
The common gate ampli fier basic circuit fig.
