Introduction -- Class D Audio Amplifiers and Data Conversion Fundamentals -- Implementation of the SDM -- Measured Prototypes and Experimental Results -- Conclusions.
This book focuses on the design of a 3rd Order CT-ΣΔM 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.
