Abstract
One embodiment provides a system comprising a single DC voltage source and a Class-D amplifier comprising at least one DC/DC converter operated by the single DC voltage source. The amplifier is configured to receive an input signal for power amplification, and generate, via the at least one DC/DC converter, a DC output voltage that approaches or exceeds a DC supply voltage from the single DC voltage source. A gain of the amplifier is a ratio of the output voltage level to the input signal. A steady-state operating point of the at least one DC/DC converter is zero output.
