A CS amplifier utilizes an NMOS transistor

with L=0.36μm and W/L=10; it was fabricated in a 0.18μm CMOS process for which μnCox=387μA/V2 and VA=5V/μm. Find the values of gm and A0 obtained at ID=10μA,100μA and 1mA.

Since,

W/L=10 and L=0.36μm

Therefore, W=3.6μm

For CS Amplifier :-

gm=2μnCox(W/L)ID

Ao=VA2μnCox(WL)ID

(i) For ID=10μA,

$g_m = \sqrt {(2)(387 …
