ABSTRACT:
An amplifier includes an input circuit for alternately selecting input signals to be compared and a first bias circuit for producing self-bias when one of the input signals is selected. A second bias circuit stores the self-bias for use in the amplifier when the other of the input signals is selected for rejecting noise which may accompany power supply voltage applied to the amplifier.
