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

This book focuses on the design of a 3rd Order CT-[Sigma Delta]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.
