Find required value of compensating miller capacitance

Reference no: EM131022010

An op amp with an open-loop voltage gain of 80 dB and poles at 105 Hz, 106 Hz, and 2 × 106 Hz is to be compensated to be stable for unity β. Assume that the op amp incorporates an amplifier equivalent to that in Fig. 11.40, with C1 = 150 pF, C2 = 5 pF, and gm = 40 mA/V, and that fP1 is caused by the input circuit and fP2 by the output circuit of this amplifier. Find the required value of the compensating Miller capacitance and the new frequency of the output pole.
