Consider a design of the cascode op amp of Fig. 13.10 for which I = 400 μA and IB = 250 μA. Assume that all transistors are operated at / VOV / = 0.2 V and that for all devices, / VA / = 10 V. Find Gm, Ro, and Av . Also, if the op amp is connected in the feedback configuration shown in Fig. P13.22, find the voltage gain and output resistance of the closed-loop amplifier.
