AC equivalent circuit

$A_V(Voltage Gain):$

$A_V = - gm (R_D || r_d)$

But, $gm = gmo \sqrt \frac{IDSq}{IDSS}$....(1)

IDSq can be found using DC analysis, For DC analysis all connected capacitor acts as open circuit hence circuit becomes,

We know that,

$IDS = IDSS(1- \frac{VGS}{V_P})^2$

$IDS = …
