9.55 An NMOS differential pair is biased by a current source I = 0.2 mA having an output resistance R SS =100 k. The amplifier has drain resistances RD =10 k, using transistors with knW/L = 3 mA/V2, and ro that is large. If the output is taken differentially and there is a 1% mismatch between the drain resistances, find  Ad ,  Acm , and CMRR.
