Problem 4. [30 pts] Resistance calculation VDD IB VD M1 R r₁ B VDD IB VD M1 R 1₂ C1 VB DD IB VD M1 R T3 Reference Added subject Comment OL Given three different circuits above with resistor R, transistor M1 (gm1, ro1) and a positive current bias IB and positive bias voltage VB such that M1 is in saturation. Also assume that C1 is very large that it can be considered as DC block, but a signal short. Draw small signal models of the circuits and find the expressions for r₁, r2, and r³.
