The design of an analog-to-digital converter or digital-to-analog converter is one of the most fascinating tasks in micro-electronics. In a converter the analog world with all its intricacies meets the realm of the formal digital abstraction. Both disciplines must be understood for an optimum conversion solution. In a converter also system challenges meet technology opportunities. Modern systems rely on analog-to-digital converters as an essential part of the complex chain to access the physical world. And processors need the ultimate performance of digital-to-analog converters to present the results of their complex algorithms. The same progress in CMOS technology that enables these VLSI digital systems creates new challenges for analog-to-digital converters: lower signal swings, less power and variability issues. Last but not least, the analog-to-digital converter must follow the cost reduction trend. These changing boundary conditions require micro-electronics engineers to consider their design choices for every new design. Analog-to-Digital Conversion discusses the different analog-to-digital conversion principles: sampling, quantization, reference generation, nyquist architectures and sigma-delta modulation. It also presents an overview of the state-of-the-art in this field and focuses on issues of optimizing accuracy and speed while reducing the power level. A lot of background knowledge and practical tips complement the discussion of basic principles, which makes Analog-to-Digital Conversion also a reference for the experienced engineer.

This textbook is appropriate for use in graduate-level curricula in analog to digital conversion, as well as for practicing engineers in need of a state-of-the-art reference on data converters.  It discusses various analog-to-digital conversion principles, including sampling, quantization, reference generation, nyquist architectures and sigma-delta modulation.  This book presents an overview of the state-of-the-art in this field and focuses on issues of optimizing accuracy and speed, while reducing the power level. This new, second edition emphasizes novel calibration concepts, the specific requirements of new systems, the consequences of 45-nm technology and the need for a more statistical approach to accuracy.  Pedagogical enhancements to this edition include more than twice the exercises available in the first edition, solved examples to introduce all key, new concepts and warnings, remarks and hints, from a practitioner’s perspective, wherever appropriate.  Considerable background information and practical tips, from designing a PCB, to lay-out aspects, to trade-offs on system level, complement the discussion of basic principles, making this book a valuable reference for the experienced engineer. Covers the most relevant developments in analog-to-digital conversion, in a pedagogical framework suited for both graduate-level courses and professionals; Updates the first edition of this book to include novel calibration concepts, the specific requirements of new systems, the consequences of 45-nm CMOS technology and some first results with metal-gate 28-nm technologies; Emphasizes the need for a more statistical approach to accuracy, not only as a theoretical exercise, but also to calculate circuit (mal)function and design yield; Provides insight on how to choose parameters for designing circuits, using extended examples of how to make that choice for an amplifier, a track-and-hold circuit, a full-flash converter, a conversion stage or a filter for sigma-delta modulator; Includes more than twice the exercises of the first edition, as well as solved examples to help introduce each new concept.
