An NMOS amplifier is to be designed to provide a 0.20-V peak output signal across a 20-kΩ load that can be used as a drain resis
tor.
(a) If a gain of at least 10V/V is needed, what gm is required?
(b) Using a dc supply of 1.8V, what values of ID and VOV would you choose?
(c) What W/L ratio is required if μnCox=200 μA/V^2? If Vt =0.4V, find VGS.
