(b) If the op-amp is realized by the circuit shown in Fig. 4( find the low-frequency gain and estimate the dominant pole pi as a function of the appropriate small-signal parameters and capacitor values. The unity-gain buffer has very high input resistance and very low output resistance. Assume that the voltage gain of the 2nd stage is very large and make any appro priate approximations. Then find the expression for the unity-gain frequency assuming that it is well within the...
