The op amp in the circuit of Fig. has an open-loop gain of 105 and a single-pole roll off with ω3dB = 10 rad/s.
(a) Sketch a Bode plot for the loop gain.
(b) Find the frequency at which |Aβ| = 1, and find the corresponding phase margin.
(c) Find the closed-loop transfer function, including its zero and poles. Sketch a pole-zero plot. Sketch the magnitude of the transfer function versus frequency, and label the important parameters on your sketch.
