Traditionally, switching amplifiers (i.e., class-D and class-G) with negative supply rails had issues with direct current (DC) power loss, included large external capacitors, had a comparative reduction in efficiency, and oftentimes included separate power management circuits. Here, a class-D amplifier is provided with an output stage that provides negative supply voltages, positive supply voltages, and ground. Essentially, this amplifier provides some of the benefits of the conventional amplifiers without the drawbacks.
