Klappentext zu „Systematic Design of CMOS Switched-Current Bandpass Sigma-Delta Modulators for Digital Communication Chips “
Systematic Design of CMOS Switched-Current Bandpass Sigma-Delta Modulators for Digital Communication Chips discusses architectures, circuits and procedures for the optimum design of bandpass sigma-delta (SD) A/D interfaces for mixed-signal chips in standard CMOS technologies. The book differs from others in the very detailed and in-depth coverage of switched-current (SI) errors, which supports the design of high performance SI chips. The book starts with a tutorial presentation of the fundamentals of bandpass SD converters, their applications in communications and their most common architectures. It then presents the basic SI building blocks required for their implementation and analyzes in great detail the operation of these blocks. The influence of SI errors on the performance of the SD modulators (SDMs) is also studied. The outcome is a unique set of models which can be employed with a double purpose: namely, to support iterative procedures employed in mapping specifications onto design parameters; and to allow for accurate behavioural time-domain simulation using MATLAB-like tools. The book is completed with two case studies corresponding to modulators for AM digital radio receivers.
