Description
Understanding DeltaSigma Data Converters brings readers a clear understanding of the principles of deltasigma (DeltaSigma) converter operationanalog to digital and digital to analog. It introduces the best computeraided analysis and design techniques available. With an understanding of the great versatility of the DeltaSigma converter, readers can apply their new knowledge to a wide variety of applications, including digital telephony, digital audio, wireless and wired communications, medical electronics, and industrial and scientific instrumentation. The authors make the material accessible to all design engineers by focusing on developing an understanding of the physical operation rather than getting mired in complex mathematical treatments and derivations.
Written for entrylevel readers, the publication has a natural flow that begins with basic concepts, enabling the readers to develop a solid foundation for the book's more complex material. The text, therefore, starts with a general introduction to the DeltaSigma converter, including a brief historical overview to place it in context. Next, the publication introduces the firstorder DeltaSigma modulator, covering oversampling, noiseshaping, decimation filtering and other key concepts. Then, using the firstorder modulator as a foundation, second and higherorder modulators are presented and analyzed. Finally, the authors delve into implementation considerations and present several design examples using the DeltaSigma Toolbox.
Everything needed to facilitate quick comprehension and help readers apply their newly learned principles is provided:Simplified methods to understand complicated concepts such as spectral estimation and switched noiseReferences that lead to indepth analysis of specialized topicsFigures and charts that illustrate complex design issuesConclusion section at the end of each chapter that highlights the key pointsReference manual for the DeltaSigma Toolbox, along with numerous practical examples that illustrate the use of the Toolbox
This is essential reading for all design engineers who want to learn and fully harness the powerful capabilities of DeltaSigma data converters. Upperlevel undergraduates and graduate students will find the book's logical organization and clear style, coupled with numerous practical examples, a great entry into the field.
