✦ Synopsis

Continuous-Time Sigma-Delta Modulation for A/D Conversion in RadioReceivers describes the design and theory of continuous-time sigma-delta modulators for analog-to-digital conversion in radio receivers. The book's main focus is on dynamic range, linearity and power efficiency aspects of sigma-delta modulators, which are very important requirements for use in battery operated receivers like GSM phones. An important part of the book deals with the image rejection performance of quadrature sigma-delta modulators. It is shown that techniques like dynamic-element-matching and integration of a mixer with the sigma-delta modulator greatly enhance the performance and functionality. In addition, the authors provide the reader with a theoretical overview of continuous-time sigma-delta modulation, including non-ideal effects, stability issues and different filter designs. The book's concluding chapters present chip realizations showing practical implementations of low-power and high-performance sigma-delta modulators for GSM and AM/FM radio applications.
