An amplifier has a low-frequency forward gain of 40,000 and its transfer function has three negative real

Question:

An amplifier has a low-frequency forward gain of 40,000 and its transfer function has three negative real poles with magnitudes 2 kHz, 200 kHz, and 4 MHz.

(a) If this amplifier is connected in a feedback loop with f constant and with low-frequency gain A₀ = 400, estimate the phase margin.

(b) Repeat (a) if A₀ is 200 and then 100.
