Advanced Data Converters, by Gabriele Manganaro, Cambridge University Press, 2011, ISBN: 978-1-10700-557-0.
Advanced Data Converters offers many insights into the mind and kit bag of a highly knowledgeable and experienced converter designer. Dr. Gabriele Manganaro is Engineering Director of high-speed data conversion at Analog Devices. The theme of the book, as stated in his foreword, is this: “In order to meet different and often conflicting requirements, circuit designers have developed very different converter architectures, each with its own strengths, weaknesses, and associated tradeoffs. However, ever-increasing application demands, together with the rapidly varying design constraints and benefits offered by new process technologies, have recently led to (a) the introduction of brand new converter architectures, (b) the revival of older architectures thought to be fallen perhaps a bit into disuse, and (c) the recent popularity of hybrid architectures combining multiple classic converter styles into mixed ones to achieve a superior overall performance.”
The book’s six chapters offer a stimulating cornucopia of circuit techniques, ideas, and examples, profusely illustrated and supported with extensive documentation by some 416 references to the literature—a veritable catalog of design concepts.
Chapter 1, “The Need for Data Converters,” discusses “the digital revolution in an analog world,” with examples of applications in sensing, digital audio, wireless communications infrastructure, and health care and life sciences, and continues with “challenges and opportunities offered by recent technology advancements.”
Chapter 2 is a “Refresher of the basics,” including such topics as mapping needs to performance metrics, static and dynamic performance metrics, classic architectures, and trimming and calibration. Also included is a discussion of figures of merit, which offers a useful background for the Chapter 5 discussion: “Trends in data conversion.”
Chapter 3 discusses “Advanced analog to digital converters,” which includes such topics as “The renaissance of some classic ADCs” (folding and interpolation ADCs, dynamic ADCs, successive-approximation ADCs, continuous time delta-sigma ADCs, and incremental and extended counting ADCs), emerging architectures and techniques, hybrid ADCs, time-interleaving, and a discourse, “What about pipelined ADCs?”
Chapter 4 turns to “Advanced digital-to-analog converters,” which is principally about current steering DACs. Topics include architecture and segmentation, static linearity (limitations, intrinsic matching, calibration, advanced calibration), dynamic linearity (finite output impedance, common source node of the steering switches, switches and their drivers, timing skews, and other causes of performance degradation), layout and floorplanning, dynamic element matching in segmented Nyquist-rate DACs, and signal processing techniques.
Chapter 5 discusses trends in ADCs (performance, CMOS scaling, architectural and applications considerations) and DACs.
Chapter 6 is a brief concluding chapter, followed by References and Index.
The author has aimed this book at graduate students focusing in mixed-signal electronics and to semiconductor professionals developing or using A/D and D/A converters. It should be in the hands of anyone seriously interested in converter design.
