Estimate the small-signal gain a 5 vodyvid of the op amp for the case in which both differential input pairs are active. Assume ID11p 5 ID11n 5 100 A, ID7 5 ID8 5 ID9 5 ID10 5 125 A, n 5 2p 5 1y(10...

Estimate the small-signal gain a 5 vodyvid of the op amp for the case in which both differential input pairs are active. Assume ID11p 5 ID11n 5 100 A, ID7 5 ID8 5 ID9 5 ID10 5 125 A, n 5 2p 5 1y(10 V), x 5 0.1, and VOV 5 0.25 V throughout. Hint: use half-circuit analysis.

For the op amp of let VAn 5 1.5VAp 5 45 V and 0p 5 150. Moreover, let IC11p 5 IC11n 5 50 A, and assume the CMFN keeps IC3 5 IC4 5 IC5 5 IC6 5 35 A. Estimate the small-signal gain a 5 vodyvid if vIC is (a) near VEE, (b) near VCC, and (c) about halfway between VEE and VCC. Hint: use half-circuit analysis.
