ResumenSystematic Design of CMOS Switched-Current Bandpass Sigma-Delta Modulators for Digital Communication Chips gives a systematic methodology for designing ΣΔ Modulators (ΣΔMs), specially those of the bandpass type, realized in digital CMOS technologies by using switched-current (SI) circuits. For this purpose, an analysis of SI error mechanisms as well as their influence on the performance of ΣΔMs is presented in a detailed and comprehensive style. On the one hand, the depth of such an analysis allows designers to get practical knowledge of the performance degradation of SI ΣΔMs through closed-form expressions that relate the modulator specifications to SI cell design parameters. On the other hand, the behavioural models derived from that study make it possible a fast and precise time-domain simulation of SI ΣΔMs, shown in the book through a simulator developed in MATLAB/SIMULINK. The architectures and circuit design methodologies presented in this book are demonstrated through two standard CMOS IC prototypes - the first silicon realizations of SI bandpass ΣΔMs - intended for AM digital radio receivers. The good performance comparison obtained with current state-of-the-art of switched-capacitor ICs demonstrates the viability of SI circuits for the realization of digital communication chips. Systematic Design of CMOS Switched-Current Bandpass Sigma-Delta Modulators for Digital Communication Chips is organized such that it can be useful for a large audience: from novices in the field to experienced ΣΔM designers. The comprehensive treatment of SI ΣΔMs given in this book will allow all of them to improve their productivity through the incorporation of circuit knowledge and CAD tools to optimize the design and to shorten the design cycle.
