A certain 741 op amp variant exhibits the resistance and transconductance values of but with different frequency characteristics because of a different fabrication process. Before compensation the 2nd stage contributes a pole pair with its stray input and output capacitances C1 5 2 pF and C2 5 4 pF, and the rest of the circuitry contributes a 3rd pole frequency at 7.5 MHz. (a) Find the Miller capacitance Cc that will ensure m 5 758 for negative-feedback operation with 5 1. What is the slew rate SR? (b) Obtain an expression for the loop gain T(jf).
