This book is the first graduate-level textbook presenting a comprehensive treatment of Data Converters. The advancement of digital electronics urged the availability of a still missing support for teaching and self-learning analog-digital interfaces at many levels: the specification, the conversion methods and architectures, the circuit design and the testing. Data Converters is a textbook that is also essential for engineering professionals as it was written for responding to a shortage of organically organized material on the topic. The book assumes a solid background in analog and digital circuits as well as a working knowledge of simulation tools for circuit and behavioral analysis. A background on statistical analysis is also helpful, though not strictly necessary. TOC:1. Background Elements.- 2. Data Converters Specifications.- 3. Nyquist-Rate D/A Converters.- 4. Nyquist Rate A/D Converters.- 5. Circuits for Data Converters. 6.- Oversampling Data Converters.- 7. Digital Enhancement Techniques.- 8. Testing of D/A and A/D Converters.
