Abstract
A three-level half-bridge PWM amplifier includes a PWM generator and an output stage. The PWM generator changes a width of a pulse at a first level or a second level according to amplitude of an input signal and outputs a three-level PWM output signal having the first level, the second level, and a reference level. The output stage drives an output node connected to a terminal of a load to a first power supply voltage, a second power supply voltage, or a third power supply voltage based on the three-level PWM output signal. Accordingly, unnecessary static current consumption is reduced, thereby increasing efficiency.
