Response to the following question:
An NMOS differential pair is biased by a current source I = 0.2 mA having an output resistance RSS =100 kΩ The amplifier has drain resistances RD =10 kΩ, using transistors with kΩ nW/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.
