Design and Implementation of Sigma Delta Modulators ( M) for Class D Audio Amplifiers using Differential Pairs

This book focuses on the design of a 3rd Order CT-M where the integrator stages of the filter are implemented with Bipolar-Junction Transistors (BJT) differential pairs. These circuits are fully analyzed and the design method is carefully explained. The design method is validated through experimental measurements of several prototype circuits.

Introduces readers to one of the premier solutions in signal conversion, for low frequency, high-resolution applications Describes a novel approach for the design of the integrator stages of the modulator Explains how to analyze and design a continuous time Sigma-Delta Modulator (S?M) using only differential pairs as amplifiers Includes supplementary material: sn.pub/extras
