D 8.44 Consider the CMOS amplifier of Fig. 8.16(a) when fabricated with a process for which kn = 4kp = 400 μA/V2,  Vt  = 0.5 V, and  VA  = 5 V. Find IREF and (W/L)1 to obtain a voltage gain of –40 V/V and an output resistance of 100 k. Recall that Q2 and Q3 are matched. If Q2 and Q3 are to be operated at the same overdrive voltage as Q1, what must their W/L ratios be?
