For the circuit in Fig. 9.14, assuming α = 1 and IRC =5 V, use Eqs. (9.48) and (9.49) to find iC1 and iC2, and hence determine vod =vC2 -vC1 for input differential signals vid ≡ vB1 - vB2 of 2 mV, 5 mV, 10 mV, 15 mV, 20 mV, 25 mV, 30 mV, 35 mV,and 40 mV. Plot vod versus vid , and hence comment on the amplifier linearity. As another way of visualizing linearity, determine the gain ( vo/vid) versus vid . Comment on the resulting graph.
