Topic : Digital Sigma Delta Modulators: An Overview

Authors:Anuja Askhedkar || Dr. G. H. Agrawal

Abstract:The audio devices use Sigma Delta DAC (Digital to Analog Converter) an essential block at the receiver side. This DAC has many blocks out of which noise shaping loop also known as Sigma Delta modulator is all digital circuit. The area and power consumption and speed of this block affect the performance of the entire DAC. There are various types of Sigma Delta modulators available. Different methods are developed for the performance improvement of these modulators. This paper discusses in detail various types of digital Sigma-Delta modulators and different performance improvement techniques available.

Keywords: The area, delay, error feedback, MASH, power Sigma Delta DAC
