The purpose of this book is to help students, engineers, and scientists in the design and use of data converters, either as stand alone parts or used on a mixedanalog-digitalIC.Forclassuse,eachchapterincludesmanyproblemsfor illustrating the practical applications of the text. In addition, the book includes examples and insets outlining key aspects of the studied topics. The contents of this book stem largely from a course on Data Converters givenattheTexasA&MUniversity, CollegeStation, attheUniversityofTexas, Dallas and more recently at the University of Pavia, Italy. The course assumes that the students have a working knowledge on analog circuit design, layout and are familiar with the principles of operation of transistors. The book contains nine Chapters. Chapter 1 deals with the background knowledge necessary to properly understand and design data converters by providingthetheoreticalimplicationsofdataconversionandmakingthereader aware of the limits of the approximations used for studying a data converter. In addition, the chapter recalls the mathematical tools used for analysis and characterization of sampled-data systems. Chapter 2 helps in a proper understanding of data converter speci?cations.

The chapter also clari?es the de?nitions of technical terms used in manufactur- supplied speci?cations.

Then, resistor based and capacitor-based architectures are discussed. Finally, the chapter studies the architectures that obtain the DAC function by steering unary or binary-weighted current sources and at the end brie?y m- tions special architectures.
