CMOS Cascade Sigma-Delta Modulators for Sensors and Telecom: Error Analysis and Practical Design starts with a tutorial presentation of the fundamentals of low-pass sigma-delta modulators, their applications, and their most common architectures. It then presents an exhaustive analysis of SC circuit errors with a twofold outcome. On the one hand, compact expressions are derived to support design plans and quick top-down design. On the other, detailed behavioral models are presented to support accurate verification. This set of models allows the designer to determine the required specifications for the different modulator building blocks and form the basis of a systematic design approach. The book is completed in subsequent chapters with the detailed presentation of three high-performance modulator ICs: the first two are intended for DSL-like applications, whereas the third one is intended for automotive sensors.

CMOS Cascade Sigma-Delta Modulators forSensors and Telecom: Error Analysis and Practical Design contains highly valuable information that is structured to give the reader the necessary insight on how to design SC sigma-delta modulators.

Tutorial presentation of the fundamentals of low-pass sigma-delta (SD) converters, their main applications and their most common architectures Detailed and in-depth analysis of switched-capacitor (SC) errors from the building-block level to the modulator level, with a triple purpose To provide procedures to map modulator specifications onto design parameters To obtain compact expressions for fast estimation of the error influence on the modulator performance To obtain accurate models that can be incorporated in time-domain behavioral simulation tools To give practical guidelines on the architecture selection, sizing, and electrical implementation of SC SD ICs and to illustrate them trough three case study chips in CMOS deep-submicron technologies intended for broadband telecom and for sensor applications with performances in the state of the art
