9.65 A bipolar differential amplifier with I = 0.5 mA utilizes transistors for which V A = 50 V and β = 100. The collector resistances R C = 5 k and are matched to within 10%. Find: (a) the differential gain (b) the common-mode gain and the CMRR if the bias current I is generated using a simple current mirror (c) the common-mode gain and the CMRR if the bias current I is generated using a Wilson mirror. (Refer to Eq. 8.95 for R o of the Wilson mirror.)
