Draw a telescopic-cascode op amp similar to the first stage in Fig. 6.25 except use an n-channel input pair and a high-swing p-type cascode current-mirror load. Calculate the maximum output swing in terms of the common-mode input voltage. Deter-mine the optimum common-mode input voltage for maximizing the output swing, and calculate the swing with this common-mode input voltage under the same assumptions given in Problem 6.16.
