Abstract
A class SM amplifier is provided having a threshold circuit with a plurality of threshold levels for generating a plurality of threshold signals. In response to an input signal passing a particular threshold level, the threshold circuit generates as an output a particular threshold signal. A voltage supply is provided having a plurality of voltage levels. The class SM amplifier includes a plurality of transistors coupled to a load and the threshold circuit, and the plurality of voltage levels from the voltage supply. The transistors switch a particular voltage level across the load in response to a particular threshold signal from the threshold circuit. The plurality of voltage levels are adjusted to approximate the input signal.
