Figure 2
7. A certain op-amp has an open-loop response curve as shown in Figure 3. A particular application
requires a 30 dB closed-loop midrange gain. To achieve a 30 dB gain, compensation must be
added because the 30 dB line intersects the uncompensated open-loop gain on the -40
dB/decade slope; therefore, stability is not assured.
a. Find out the critical frequency of the compensating network such that the -20
dB/decade slope is lowered to a point where it intersects the 30 dB gain line.
b. Sketch the ideal response curve for the compensating network.
c. Sketch the total ideal compensated open-loop response.
