Assume an op- amp has three different internal critical frequencies that are above the fT. The overall roll- off rate is
A)a constant -60 dB/decade
B)a composite of the three critical frequencies
C)the average of the three critical frequencies
D)a constant -20 dB/decade

Question

Quizplus · Accepted Answer

The overall roll-off rate of an op-amp with multiple internal critical frequencies is a composite of those frequencies, meaning the slope of the frequency response changes at each critical frequency, leading to a complex roll-off behavior rather than a single, constant rate.
