Opis

This book describes techniques for designing complex, discrete-time ADCs with signal-transfer functions that significantly filter interfering signals. The book provides an understanding of theory, issues, and implementation of discrete complex ADCs. The concepts developed in each chapter are further explained by applying them to a target application of ADCs in DTV receivers."

This book describes techniques for designing complex, discrete-time ΔΣ ADCs with signal-transfer functions that significantly filter interfering signals. The book provides an understanding of theory, issues, and implementation of discrete complex ΔΣ ADCs. The concepts developed in each chapter are further explained by applying them to a target application of ΔΣ ADCs in DTV receivers.

• Focuses on complex ΔΣ ADCs and techniques for their implementation;
• Describes techniques to alleviate problems in implementation, such as image rejection deterioration due to mismatches; 
•  Discusses advantages of filtering STFs and describes an architecture for their implementation;
• Includes Matlab, Simulink, and Mathematica code used in design and behavioral simulations for design and implementation of complex ΔΣ ADCs.
