A folded cascode 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 80% of the total dc current dissipation is to flow through the input differential pair transistors. Estimate the total current consumption required to obtain a closed-loop 3-dB bandwidth of 60 MHz.
