Repeat Problem 9.6 for the amplifier of Problem 9.4.

Data from Prob. 9.6:

The amplifier of Problem 9.5 is to be compensated by reducing the magnitude of the most dominant pole.

(a) Calculate the dominant-pole magnitude required for unity-gain compensation with 45° phase margin, and the corresponding bandwidth of the circuit with the feedback applied. Assume that the remaining poles do not move.

(b) Repeat (a) for compensation in a feedback loop with a closed-loop gain of 20 dB and 45° phase margin.
