Design and Implementation of Sigma Delta Modulators (M) for Class D Audio Ampl [Paperback]

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.Introduction.- Class D Audio Amplifiers and Data Conversion Fundamentals.- Implementation of the SDM.- Measured Prototypes and Experimental Results.- Conclusions.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
