Linear Device Applications Analysis: Delta Sigma Modulator Study.
Abstract
The report describes the operation of the delta sigma modulator A-D converter and addresses the issues of integrating and hardening the circuit. The input/output relationship of the converter is stated for both DC and AC signals. A survey of commercial converters which use delta sigma modulation or related techniques is summarized. Various current switch designs, amplifier technologies, and resistive materials are examined to develop a radiation hard, integrated circuit configuration. A design which automatically nulls offset in the converter is outlined. (Author)
