For the differential amplifier shown in Fig. P9.2, let Q1:
p(W/L) = 4 mA/V2, and assume that the bias current source has an output resistance of 30 kΩ. Find /VOV /, gm,/ Ad / , / Acm / , and the CMRR(in dB) obtained with the output taken differentially. The drain resistances are known to have a mismatch of 2%.
