In Fig. 5, VDD = 10 V, (W/L)1 = (1/0.1), (W/L)2 = (10/0.1), I1 = 100 μA, I2 = 150 μA. C1 is very large. Assume that all the transistors are in saturation. μnCox = 100 μA/V2, μpCox = 40 μA/V2, Vthn = |Vthp| = 0.5 V, λn = λp = 0 (a) For Vin = 2 V, determine VX. (b) Determine the small-signal gain of the amplifier. Figure 5
