Abstract
An amplifier adapted to generate an analog output signal in response to a digital input signal and having an output stage powered by a power-supply circuit, which generates one or more power rails for the output stage such that at least one of these power rails tracks the output signal and substantially represents a biased and half-wave rectified version of that output signal.
