Abstract

System properties can be categorized by quality indicators. In this book, these quality indicators are applied to the ΣΔ ADC architecture. This has enabled identification of important modulator performance parameters, design parameter relations, and performance-cost relations. The quality indicators predict, that to exploit the advantages of modern digitally optimized IC technologies, digitization should be carried through to all IC design abstraction levels, as far as system optimization allows. For a system on a chip these abstraction levels are: system/application level, analog IP architecture level, circuit topology level and layout level.

The generalized system property categorization in quality indicators, and the digitization at different levels of system design in this book is applied to ΣΔ modulators, leading to high quality, mixed-signal ΣΔ modulator implementations. The modulator implementations presented in the book have increased re-configurability and portability, are less sensitive to circuit imperfections, are low-cost in terms of area and power, and can be put on the market more quickly. Therefore, the modulators score high on the quality indicators.
