Abstract
An equalizer circuit includes: a pair of input terminals: a differential amplification circuit outputs, to a pair of output terminals, first signals obtained by amplifying a difference in levels of input signals supplied to the pair of input terminals; and a differential differentiation amplification circuit that outputs, to the pair of output terminals, second signals obtained by amplifying a time-varying change in the difference in the levels of the input signals supplied to the pair of input terminals.
