13.29 Consider a design of the cascode op amp of Fig. 13.10 for which I = 200 µA and IB = 150 µA. Assume that all transistors are operated at |VOV| = 0.2 V and that for all devices, |VA| = 5 V. Find Gm, Ro, and Av. Also, if the op amp is connected in the feedback configuration shown in Fig. P13.29, find the voltage gain and output resistance of the closed-loop amplifier.
