A MOSFET differential amplifier such as that is biased with a current source I=200uA. The transistors have W/L=25, k'n=200uA/V^2, VA=200 V, Cgs=40 fF, Cgd=5 fF, and Cdb=5 fF. The drain resistors are 20k-ohm each. Also, there is a 100-fF capacitive load between each drain and ground. The amplifier specified in the problem has Rss=80k-ohm and Css=0.1 pF. Find the 3-dB frequency of the CMRR.
