Repeat Problem 9.16 if the circuit of Fig. 9.59 is compensated by a capacitor of 0.05 µF

Question:

Repeat Problem 9.16 if the circuit of Fig. 9.59 is compensated by a capacitor of 0.05 µF connected from the base of Q₅to ground. Assume that the voltage gain from the base of Q₅to V_ois ˆ’500.

Data from Prob. 9.16:

The input stages of an op amp are shown in the schematic of Fig. 9.59.

Assuming that the frequency response is dominated by a single pole, calculate the frequency where the magnitude of the small-signal voltage gain | Ï…_o(jÏ‰) /Ï…_i(jÏ‰) | is unity and also the output slew rate of the amplifier.
