I observed that my CMFB circuit is limiting my amps output swing when compared to the circuit without CMFB. Does CMFB circuit really limit the output swing while forcing a common mode output at the differential output stages??
One more doubt I have is how to test the pulse response of a fully differential amplifier. One of my senior collegue tests it by connecting one output to input in a unity feedback mode and other output in open and applies the input signal to the other openly left input port. Is this a correct procedure??
