A current-mirror opamp is to be used in the feedback configuration of Fig. 6.23 with , , and all negligible. Assume the input differential pair transistors are to be biased with , and . Estimate the total current consumption required to obtain a closed-loop 3-dB bandwidth of 60 MHz. How does this result compare with that obtained for the folded cascode opamp in Problem 6.31? What is the resulting slew rate?
