The answer is provided, show the steps to get to it.

For the circuit given below, find the expression for Rin, Rout, Gm and gain. Assume all the MOSFETs operating in saturation region and consider ro = ?o. Plot the behavior of output gain vs R2. Vcc J M1 C1 R1 Vin short?!! "AC short M2 ? controls Vas of MI and M2, in parallel. Rin= R? + gm, + gmz Rout= (gmit guz) (3mi + gmz) 1- Rz (ges + Gmz) I+ Ri (gmit gmz) = (R?+R?) ||| R++ R? Gain = Gm. Rout= (Vinzo) Gm= A (Vout shorted) + R? R1+R2 R? R1+R2 it R2 Vout R? + R? Ri (gmi + grz) + ! L-R? (gmi + gmz) Rit Rz
