Response to the following question:
Design a MOS differential amplifier to operate from ±1-V power supplies and dissipate no more than 1 mW in the equilibrium state. The differential voltage gain Ad is to be 10 V/V and the output common-mode dc voltage is to be 0.2 V.
(Note: This is the dc voltage at the drains.)
Assume μnCox = 400 μA/V2 and neglect the Early effect. Specify I, RD, and W/L.
