Clearly mark results with box around. No credit for ambiguous solutions. Show derivations. Return this cover page. Good luck! UID #: Name: PROBLEM SCORE 1  2  3  4  TOTAL  2 1. A source-degenerated PMOS differential amplifier is shown below. Assume , 2 1 2 th gs d V V L W k I , 40 2 V A k and 5 L W for M 1 and M 2 in your calculation. You may ignore capacitance in your calculation for low frequencies. Answer the following questions. 1) Assuming sine-wave input drive, what input amplitude would produce 1% IM3 at the output? 2) If two identical stages of the amplifier are cascaded, repeat the calculation in 1). Take the output from the second stage....
