ABSTRACT:
A comparator includes a circuit which provides a plurality of common-mode difference signals in response to differential input signals. The circuit provides a common-mode feedback signal in response to the plurality of common-mode difference signals. The common-mode feedback signal is used to drive the common-mode level of an amplifier to a desired value.
