Sketch the small-signal differential voltage gain of the circuit shown in Fig. 4.9(a) if VDD varies from 0 to 3 V. Assume that (WIL)1-3 = 50/0.5, Vin, CM = 1.3 V, and V, = 1 V. Figure 4.9 (a) Differential pair sensing an input common-mode change; (b) equivalent circuit if M3 operates in the deep triode region; (c) common-mode input-output characteristics.
