Class-D audio amplifiers are power efficient, but do not beat, or even match, well-designed Class-AB and Class-A amplifiers on many other specs. This said, Delft University of Technology, working with ...

A critical measure for all audio components is distortion, typically specified as total harmonic distortion (THD) or total harmonic distortion + noise (THD+N). THD is defined as: ... THD+N is the rms ...

Depending on the low-distortion needs of an application, the system engineer can choose from plenty of signal amplifiers. The first step in making the right choice is to understand the typical ...

International Solid-State Circuits Conference in San Francisco always seems to make space for audio amplifier developments, and this year is no exception, with some extraordinary distortion and noise ...
