Abstract
A rail-to-rail amplifier is provided. The rail-to-rail amplifier includes a p-type differential pair, an n-type differential pair, switches, and an output stage. The switches are arranged to selectively couple either the p-type differential pair or the n-type differential pair to the output stage so that only one of the differential pairs is coupled to the output stage at a time.
