Abstract

A fully differential amplifier includes: an input stage comprising a first amplification circuit and a second amplification circuit, one of which is configured to generate a push signal and the other of which is configured to generate a pull signal, each by amplifying a differential input signal; an output stage for generating a differential output signal based on the push signal and the pull signal; and a feedback circuit for providing common mode feedback to the first amplification circuit based on the differential output signal, wherein the second amplification circuit may include a passive network for setting a common mode voltage of the push signal or the pull signal.
