3.23 A NMOS cascode amplifier with active load is shown in Fig. P3.23. It is realized using the 0.35-um CMOS devices in Table 1.5 with VDp = 3.3 V, Ipias = 100 A, (W/L)1.2.5.6 = 10 um/0.5 m, and (W/L)3,4 = 30 um/0.5 um. a. Estimate the small-signal gain, v./v, and output resistance, b. What is the total power consumption of the circuit? V Dp Q; Q4 Q. Q. Ibias Fig. P3.23
