This work is an important continuation to "CMOS: Circuit Design, Layout, and Simulation". The power of mixed-signal circuit designs, and perhaps the reason they are replacing analog-only designs in the implementation of analog interfaces, comes from the marriage of analog circuits with digital signal processing. This book builds on the fundamental material in the author's previous book, "CMOS: Circuit Design, Layout, and Simulation", to provide a solid textbook and reference for mixed-signal circuit design. The coverage is both practical and in-depth, integrating experimental, theoretical, and simulation examples to drive home the why and the how of doing mixed-signal circuit design. Some of the highlights of this book include: a practical/theoretical approach to mixed-signal circuit design with an emphasis on oversampling techniques; an accessible and useful alternative to hard-to-digest technical papers without losing technical depth; coverage of delta-sigma data converters, custom analog and digital filter design, design with submicron CMOS processes, and practical at-the-bench deadbug prototyping techniques; and hundreds of worked examples and questions covering all areas of mixed-signal circuit design. A helpful companion Web site provides worked solutions to textbook problems, SPICE simulation netlist examples, and discussions concerning mixed-signal circuit design.
