Abstract
Various embodiments of the present technology comprise a method and apparatus for a class-D amplifier. In various embodiments, the class-D amplifier operates to control an output signal during a start-up state to suppress a pop noise (start-up noise) without the need for a mute switch. The class-D amplifier may utilize a transition signal during the start-up state to prime or otherwise stabilize the output signal to suppress the pop noise.
