In the two-stage amplifier shown in Fig. 11.96, W/L = 10 μm=0:18 μm for M1-M4.
(a) Select the input dc level to obtain an output dc level of 0.9 V.
(b) Plot the frequency response and compute the low-frequency gain and the -3-dB bandwidth.
(c) Repeat (a) and (b) for W = 20 μm and compare the results.
