Abstract
A multiplexed multilevel converter amplifier. The converter is configured to generate a converter voltage. The converter voltage varies among a plurality of voltage levels. A multiplexer is comprised of at least four switches configured to generate a positive output voltage and a negative output voltage according to a configuration of the at least four switches. The positive output voltage varies between the converter voltage and a positive supply rail and the negative output voltage varies between the converter voltage and a negative supply rail. An amplifier is supplied by the multiplexer, and the amplifier generates an output voltage that varies between the positive output voltage and the negative output voltage. A control module is configured to control the configuration of the at least four switches of the multiplexer and the plurality of voltage levels of the converter voltage, such that the converter voltage is synchronized with the output voltage.
