The parameters of the transistors in Figure P10.88 are VTN = 0.6 V, VTP = −0.6 V, kn′ = 100 μA/V2, kp′ = 60 μA/V2, and λn = λp = 0.04 V−1. The width-to-length ratios of M1 and M2 are 25, and those of all other transistors are 50. The value of VGSQ is such that ID1 = 80 μA, and all transistors are biased in the saturation region. Determine the smallsignal voltage gain Av = vo/vi. Figure P10.88
