Question:
Assume that the CMFB circuit in the example in Section 12.6.1 is changed so that the CM-sense amplifier has a low-frequency gain |acms0| = 2.5. Determine the compensation capacitor C needed in the op amp to assure that the CMC and DM feedback loops in the example have a phase margin of 45◦ or larger.
