*7.26 An NMOS amplifier is to be designed to provide a 0.20-V peak output signal across a 20-k load that can be used as a drain resistor. If a gain of at least 10 V/V is needed, what gm is required? Using a dc supply of 1.8 V, what values of I D and VOV would you choose? What W/L ratio is required if μnCox = 200 μA/V2? If Vt = 0.4 V, find VGS.
