9.110 A bipolar differential amplifier such as that shown in Fig. 9.36(a) has I = 0.4 mA, VA =40 V, and β = 150. Find G m, Ro, Ad, and Rid. If the bias current source is implemented with a simple npn current mirror, find REE, Acm, and CMRR. If the amplifier is fed differentially with a source having a total of 30 k resistance (i.e., 15 k in series with the base lead of each of Q1 and Q2), find the overall differential voltage gain.
