About this title

Synopsis

The interest for :I:~ modulation-based NO converters has significantly increased in the last years. The reason for that is twofold. On the one hand, unlike other converters that need accurate building blocks to obtain high res­ olution, :I:~ converters show low sensitivity to the imperfections of their building blocks. This is achieved through extensive use of digital signal pro­ cessing - a desirable feature regarding the implementation of NO interfaces in mainstream CMOS technologies which are better suited for implementing fast, dense, digital circuits than accurate analog circuits. On the other hand, the number of applications with industrial interest has also grown. In fact, starting from the earliest in the audio band, today we can find :I:~ converters in a large variety of NO interfaces, ranging from instrumentation to commu­ nications. These advances have been supported by a number of research works that have lead to a considerably large amount of published papers and books cov­ ering different sub-topics: from purely theoretical aspects to architecture and circuit optimization. However, so much material is often difficultly digested by those unexperienced designers who have been committed to developing a :I:~ converter, mainly because there is a lack of methodology. In our view, a clear methodology is necessary in :I:~ modulator design because all related tasks are rather hard.

Synopsis

"Top-Down Design of High-Performance Sigma-Delta Modulators" discusses architectural and circuit considerations for optimizing the design of oversampled A/D interfaces for mixed-signal CMOS ASICs. The necessary mathematical background is presented in a detailed and comprehensive style, suitable for novices in the field. Practical recipes on how to get the maximum performance from these kinds of circuits are presented and illustrated through three converter prototypes in CMOS submicron technologies. A distinctive feature of this book is the presentation of a systematic methodology for increasing the productivity of engineers in the design of high-performance modulators. It uses optimization at the architecture and the circuit levels, together with hierarchical transmission of the specifications among levels.The major tasks of architecture selection, architecture sizing and building block sizing are supported by dedicated CAD tools, thus allowing designers to obtain demanding modulator specifications in short design cycles. "Top-Down Design of High-Performance Sigma-Delta Modulators" is organized such that it can be used for a graduate course on SigmaDelta modulator design.

In addition, the book is a valuable reference for designers who want to improve their productivity in the design of oversampled mixed-signal interfaces.
