An op-amp with an open-loop gain of 5000 and poles at 104 , 105
, and 106 Hz is to be compensated by the addition of a fourth
dominant pole to operate stably with unity feedback. a) What is the
frequency of the required dominant pole? [5 points] b) What are the
resulting phase [8 points] and gain margins [7 points]? c) Instead
of adding a fourth pole, to what frequency should the pole at 104
Hz be shifted for stable operation with unity feedback [5
points]?
