Abstract
Although distortion is a key characteristic of class-D audio amplifiers, in practice most design effort is spent on robustness and the mitigation of audible artifacts. This paper explores some topics from these relatively unfamiliar areas of design. The switching nature of class-D amplifiers involves problems and solutions that are typical for class-D.
