数据转换器的经典－The Data Conversion Handbook

revolution1983

The second chapter, fundamentals of sampled-data systems, sets thestage for hardware design-discussing coding and quantizing, samplingtheory, data-converter ac errors, general data-converterspecifications, and definitions of specifications.

The fourth chapter covers a wide range of data-converter processtechnologies, from the early vacuum-tube converters, throughsolid-state modular and hybrid converters, to bipolar,complementary-bipolar (CB), and CMOS integrated-circuit processes. Alsocovered are thin-film resistor and calibration processes; and there isa section on smart partitioning: optimizing performance, space, andcost by intelligent choice of process partitioning within a package.

Chapter 5 provides in-depth discussions of a wide variety of testingtechniques for static and dynamic performance characteristics of DACsand ADCs. The following chapter, interfacing to data converters, has amajor section devoted to analog interface considerations in driving ADCinputs. Other sections in this chapter include ADC and DAC digitalinterfaces (and related issues), buffering DAC analog outputs,data-converter voltage references, and sampling-clock generation.

Chapter 7, data-converter support circuits, discusses in depth suchimportant analog auxiliary circuits as voltage references; low-dropout(LDO) linear regulator circuits; analog-, digital-, and video switches(including cross-point types) and multiplexers; and sample(track)-and-hold circuits.

The foregoing chapters, some 60% of the book, amount to a virtualappetizer for the banquet of tutorial material in the last twochapters: data-converter applications (Chapter 8) and hardware designtechniques (Chapter 9). These two chapters amount to a practical courseon design solutions and techniques that can enrich the portfolio of anydesigner, from the technician and recent graduate to the hardenedsystems engineer.

The wide-ranging coverage in Chapter 8 is apportioned among eighttopics: precision measurement and sensor conditioning, multichanneldata-acquisition systems, digital potentiometers, digital audio,digital video and display electronics, software radio and IF sampling,direct digital synthesis, and precision analog microcontrollers.

Finally, Chapter 9's 185 pages are in themselves essentially a textbookfor the hardware designer. Its eight topical areas are labeled: passivecomponents, pc-board design issues, analog power-supply systems,overvoltage protection, thermal management, EMI/RFI considerations,low-voltage logic interfacing, and breadboarding & prototyping.Chapter 9 is followed by a comprehensive subject index and an indexedlisting of Analog Devices products mentioned in the book.

At last! A modern book on data conversion worthy to succeed our 1986landmark Analog-Digital Conversion Handbook (3rd edition). The DataConversion Handbook is based on the book, Analog-Digital Conversion, acomprehensive set of notes for a recent Analog Devices seminar serieson data converters.

In a digital world, A/D and D/A conversion is essential totranslate between analog real-world physical variables and the abstract1s and 0s of digital processing. The book's nine chapter titles offer ahint of its breadth, as well as its orientation to practical designingwith and use of converters: Data-converter history; Fundamentals ofsampled-data systems; Data-converter architectures; Data-converterprocess technology; Testing data converters; Interfacing to dataconverters; Data-converter support circuits; Data-converterapplications; and Hardware design techniques.

The first chapter, data-converter history, starts with the early18th-century background in hydraulic water-metering systems in theOttoman empire, then-when electricity came into use-from the 19thcentury telegraph era through the 1950s. The chapter then coversprogress-decade-by-decade-in technology, circuitry, and applications ofconverters during the late 20th and early 21st centuries. Whererelevant, historical contexts are also noted in some of the laterchapters.

The second chapter, fundamentals of sampled-data systems, sets thestage for hardware design-discussing coding and quantizing, samplingtheory, data-converter ac errors, general data-converterspecifications, and definitions of specifications.

Chapter 3, data-converter architectures, discusses DACarchitectures, ADC architectures, and sigma-delta converters. Althoughit concentrates on the most popular designs, it seeks not to neglectany significant approach. For example, among DACs it discusses theKelvin divider (string DACs), thermometer (fully decoded DACs),binary-weighted DACs, R-2R DACs, segmented DACs, oversamplinginterpolating DACs, multiplying DACs, intentionally nonlinear DACs,counting pulsewidth-modulated (PWM) DACs, cyclic serial DACs, and"other low-distortion architectures"-and naturally, the sigma-deltaconverter section includes sigma-delta DACs.

The fourth chapter covers a wide range of data-converter processtechnologies, from the early vacuum-tube converters, throughsolid-state modular and hybrid converters, to bipolar,complementary-bipolar (CB), and CMOS integrated-circuit processes. Alsocovered are thin-film resistor and calibration processes; and there isa section on smart partitioning: optimizing performance, space, andcost by intelligent choice of process partitioning within a package.

Chapter 5 provides in-depth discussions of a wide variety oftesting techniques for static and dynamic performance characteristicsof DACs and ADCs. The following chapter, interfacing to dataconverters, has a major section devoted to analog interfaceconsiderations in driving ADC inputs. Other sections in this chapterinclude ADC and DAC digital interfaces (and related issues), bufferingDAC analog outputs, data-converter voltage references, andsampling-clock generation.

Chapter 7, data-converter support circuits, discusses in depth suchimportant analog auxiliary circuits as voltage references; low-dropout(LDO) linear regulator circuits; analog-, digital-, and video switches(including cross-point types) and multiplexers; and sample(track)-and-hold circuits.

The foregoing chapters, some 60% of the book, amount to a virtualappetizer for the banquet of tutorial material in the last twochapters: data-converter applications (Chapter 8) and hardware designtechniques (Chapter 9). These two chapters amount to a practical courseon design solutions and techniques that can enrich the portfolio of anydesigner, from the technician and recent graduate to the hardenedsystems engineer.

Finally, Chapter 9's 185 pages are in themselves essentially atextbook for the hardware designer. Its eight topical areas arelabeled: passive components, pc-board design issues, analogpower-supply systems, overvoltage protection, thermal management,EMI/RFI considerations, low-voltage logic interfacing, andbreadboarding & prototyping. Chapter 9 is followed by acomprehensive subject index and an indexed listing of Analog Devicesproducts mentioned in the book.

This book will be a valuable addition to the library of thestudent, the practicing circuit design engineer and technician, andanyone else who needs a good practical grasp of what is needed for asuccessful marriage between the analog and digital worlds.

I bought this book after the High Speed Analog seminar given by AnalogDevices. Several chapters show modern types of data converters,interfacing to the analog signal sources and to the digital circuitry.It is a must for engineers who want not only to use the data conversionproducts but also understand what is going on there. I would highlyrecommend this book also to teachers dealing with this subject as anexcellent source of information on state of art data converterspresently available on the market.
