All Digital High Resolution Class D Amplifier Designs Using Power Supply Feed-Forward and Signal Feedback
This paper describes digital input Class D amplifier design using a custom integrated circuit controller. Sophisticated digital Pulse Width Modulation, combined with digital Feed-Forward and Feedback paths, yields high resolution amplifiers. A powerful DSP is included in the controller to support amplifier control and allows comprehensive audio signal processing, including loudspeaker load compensation, EQ, time alignment, room acoustics compensation, bass enhancement, loudspeaker driver protection, virtual surround and other audio signal processing tasks. Power supply Feed-Forward and closed-loop Feedback technology correct for non-linearity and other distortion-inducing mechanisms.
