A bipolar differential amplifier

Reference no: EM131037570

9.65 A bipolar differential amplifier with I =0.5 mAutilizes transistors for which VA = 50 V and β = 100. The collector resistances RC = 5 kΩ 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 Ro of the Wilson mirror.)
