Abstract
An amplifier. The novel amplifier includes a first circuit for receiving and amplifying an input signal and outputting an output signal, and a second circuit for supplying power to the first circuit, wherein the power supplied varies in accordance with variations in the output signal. The second circuit includes a bootstrapping circuit adapted to regulate the voltages across any transistors in the signal path such that the voltages remain constant. In an illustrative embodiment, the second circuit bootstraps the voltages across a PMOS current source that acts as the load to an input stage, as well as a Darlington pair in an output stage of the amplifier.
