Product Description: Learn how to harness the
power of delta-sigma data converters
Understanding Delta-Sigma Data Converters brings readers a clear understanding of the principles of delta-sigma (ΔΣ) converter operationanalog to digital and digital to analog. It introduces the best computer-aided analysis and design techniques available. With an understanding of the great versatility of the ΔΣ 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 entry-level 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 ΔΣ converter, including a brief historical overview to place it in context. Next, the publication introduces the first-order ΔΣ modulator, covering oversampling, noise-shaping, decimation filtering and other key concepts. Then, using the first-order modulator as a foundation, second and higher-order modulators are presented and analyzed. Finally, the authors delve into implementation considerations and present several design examples using the Delta-Sigma 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 noise References that lead to in-depth analysis of specialized topics Figures and charts that illustrate complex design issues Conclusion section at the end of each chapter that highlights the key points Reference manual for the Delta-Sigma 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 ΔΣ data converters. Upper-level 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.
Summary: grade B

This is certainly one of the best book written on delta-sigmas but a good book on the subject has yet to be written.
There is a chapter dedicated to design examples which is quite good. Multi-bit versus single bit, high order versus low order modulators gets good coverage. The weakness is the organisation of similar information dispersed in several chapters. The authors tried to avoid an overly mathematical style of writting but one wishes a little less hand waving. Many pages of text could have been replaced by simple and unequivocal mathematical derivations. I found the page layout is below average and exposition of ideas and concepts too superficial. This book would have been ok if it was reasonably priced given the average quality of its content but it is twice what it should be.
Summary: A Univied, Consistent Approach
Rating: 5
Much of the recent literature on digital signal processing has concentrated on the digital aspects of the task. The result is a surplus of books on the digital signal processing chips and programming techniques.
In the real world you have a signal and you need it digitized, or you have some digital data and you need a real life signal that you can send out somewhere. The real world refuses to become digital, its analog.
The literature on how to do this aspect has been sparse. And most of what does exist is in the form of a book by many authors. Their different writing style, different assumptions on the background of the readers and the inevitable disconnects between chapters make a consistent flow impossible.
In this book Dr. Temes, a professor at Oregon State brings a solid theoretical background to the writing. Dr. Schreier, a senior design engineer at Analog Devices brings an understanding of what is possible today. Both men have a wealth of experience in the subject and an ability to convey their experience and knowledge to the reader.
