Convention Paper

Power Digital-to-Analog Conversion Using Sigma-Delta Pulse Inversion Techniques

Authors: Magrath, Anthony J.; Sandler, Mark B.

AES Convention 99 · Paper 4106 · October 1995

Abstract

A data conversion technique suitable for power digital-to-analog converters is described, based on a modified sigma-delta modulator. The pulse-repetition frequency in the bitstream is reduced in order to increase the efficiency in the power output switching stage. The system offers pulse-repetition frequencies comparable to pulse-width modulation-based digital-to-analog converters, but with higher linearity and more than a thirty-fold reduction in clock frequency.
