For the following problem, include channel length modulation for all transistors. Ignore body effect and all capacitors. Assume all transistors are biased in saturation. Transistors M1 and M2 are matched, and M3 and M4 are matched. (a) Draw a schematic of the equivalent small-signal circuit. (b) Derive an expression for the low-frequency small-signal gain of the circuit. (c) Derive an expression for the CMRR, CMRR = Adm/Acm.
