Available in PDF, EPUB and Kindle. Book excerpt: Modern complementary metal oxide semiconductor (CMOS) digital-to-analog converters (DACs) are limited in their bandwidth due to technological constraints. These limitations can be overcome by parallel DAC architectures, which are called interleaving concepts. Christian Schmidt analyzes the limitations and the potential of two innovative DAC interleaving concepts to provide the basis for a practical implementation: the analog multiplexing DAC (AMUX-DAC) and the frequency interleaving DAC (FI-DAC). He presents analytical and discrete-time models as a theoretical foundation and develops digital signal processing (DSP) algorithms to compensate the analog impairments. Further, he quantifies the impact of various limiting parameters with numerical simulations and verifies both concepts in laboratory experiments. About the Author: Christian Schmidt works at the Fraunhofer Heinrich-Hertz-Institute, Berlin, Germany, on innovative solutions for broadband signal generation in the field of optical communications. The studies for his dissertation were carried out at the Technische Universität Berlin and at the Fraunhofer Heinrich-Hertz-Institute, both Berlin, Germany.

This book was released on 2010-09-08 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Time-interleaved Analog-to-Digital Converters describes the research performed on low-power time-interleaved ADCs. A detailed theoretical analysis is made of the time-interleaved Track & Hold, since it must be capable of handling signals in the GHz range with little distortion, and minimal power consumption. Timing calibration is not attractive, therefore design techniques are presented which do not require timing calibration. The design of power efficient sub-ADCs is addressed with a theoretical analysis of a successive approximation converter and a pipeline converter. It turns out that the first can consume about 10 times less power than the latter, and this conclusion is supported by literature. Time-interleaved Analog-to-Digital Converters describes the design of a high performance time-interleaved ADC, with much attention for practical design aspects, aiming at both industry and research. Measurements show best-inclass performance with a sample-rate of 1.8 GS/s, 7.9 ENOBs and a power efficiency of 1 pJ/conversion-step.

Download or read book Generalized Low-Voltage Circuit Techniques for Very High-Speed Time-Interleaved Analog-to-Digital Converters written by Sai-Weng Sin and published by Springer Science & Business Media. This book was released on 2010-09-29 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analog-to-Digital Converters (ADCs) play an important role in most modern signal processing and wireless communication systems where extensive signal manipulation is necessary to be performed by complicated digital signal processing (DSP) circuitry. This trend also creates the possibility of fabricating all functional blocks of a system in a single chip (System On Chip - SoC), with great reductions in cost, chip area and power consumption. However, this tendency places an increasing challenge, in terms of speed, resolution, power consumption, and noise performance, in the design of the front-end ADC which is usually the bottleneck of the whole system, especially under the unavoidable low supply-voltage imposed by technology scaling, as well as the requirement of battery operated portable devices. Generalized Low-Voltage Circuit Techniques for Very High-Speed Time-Interleaved Analog-to-Digital Converters will present new techniques tailored for low-voltage and high-speed Switched-Capacitor (SC) ADC with various design-specific considerations.

Download or read book Smart and Flexible Digital-to-Analog Converters written by Georgi Radulov and published by Springer Science & Business Media. This book was released on 2011-01-07 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smart and Flexible Digital-to-Analog Converters proposes new concepts and implementations for flexibility and self-correction of current-steering digital-to-analog converters (DACs) which allow the attainment of a wide range of functional and performance specifications, with a much reduced dependence on the fabrication process. DAC linearity is analysed with respect to the accuracy of the DAC unit elements. A classification is proposed of the many different current-steering DAC correction methods. The classification reveals methods that do not yet exist in the open literature. Further, this book systematically analyses self-calibration correction methods for the various DAC mismatch errors. For instance, efficient calibration of DAC binary currents is identified as an important missing method. This book goes on to propose a new methodology for correcting mismatch errors of both nominally identical unary as well as scaled binary DAC currents. A new concept for DAC flexibility is presented. The associated architecture is based on a modular design approach that uses parallel sub-DAC units to realize flexible design, functionality and performance. Two main concepts, self-calibration and flexibility, are demonstrated in practice using three DAC testchips in 250nm, 180nm and 40nm standard CMOS. Smart and Flexible Digital-to-Analog Converters will be useful to both advanced professionals and newcomers in the field. Advanced professionals will find new methods that are fully elaborated from analysis at conceptual level to measurement results at test-chip level. New comers in the field will find structured knowledge of fully referenced state-of-the art methods with many fully explained novelties.“/p> DAC linearity is analysed with respect to the accuracy of the DAC unit elements.

Download or read book Integrated Analog-To-Digital and Digital-To-Analog Converters written by Rudy J. van de Plassche and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analog-to-digital (A/D) and digital-to-analog (D/A) converters provide the link between the analog world of transducers and the digital world of signal processing, computing and other digital data collection or data processing systems. Several types of converters have been designed, each using the best available technology at a given time for a given application. For example, high-performance bipolar and MOS technologies have resulted in the design of high-resolution or high-speed converters with applications in digital audio and video systems. In addition, high-speed bipolar technologies enable conversion speeds to reach the gigaHertz range and thus have applications in HDTV and digital oscilloscopes. Integrated Analog-to-Digital and Digital-to-Analog Converters describes in depth the theory behind and the practical design of these circuits. It describes the different techniques to improve the accuracy in high-resolution A/D and D/A converters and also special techniques to reduce the number of elements in high-speed A/D converters by repetitive use of comparators. Integrated Analog-to-Digital and Digital-to-Analog Converters is the most comprehensive book available on the subject. Starting from the basic elements of theory necessary for a complete understanding of the design of A/D and D/A converters, this book describes the design of high-speed A/D converters, high-accuracy D/A and A/D converters, sample-and-hold amplifiers, voltage and current reference sources, noise-shaping coding and sigma-delta converters. Integrated Analog-to-Digital and Digital-to-Analog Converters contains a comprehensive bibliography and index and also includes a complete set of problems. This book is ideal for use in an advanced course on the subject and is an essential reference for researchers and practicing engineers.

Download or read book Smart AD and DA Conversion written by Pieter Harpe and published by Springer Science & Business Media. This book was released on 2010-06-08 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of the application of semiconductors for controlling currents goes back all the way to 1926, in which Julius Lilienfeld led a patent for a “Method and apparatus for controlling electric currents” [1], which is considered the rst work on metal/semiconductor eld-effect transistors. More well-known is the work of William Shockley, John Bardeen and Walter Brattain in the 1940s [2, 3], after which the development of semiconductor devices commenced. In 1958, independent work from Jack Kilby and Robert Noyce ledto the invention of integrated circuits. A few milestones in IC design are the rst monolithic operational ampli er in 1963 (Fairchild?A702, Bob Widlar) and the rst o- chip 4-bit microprocessor in 1971 (Intel 4004). Ever since the start of the semiconductor history, integration plays an imp- tant role: starting from single devices, ICs with basic functions were developed (e. g. opamps, logic gates), followed by ICs that integrate larger parts of a s- tem (e. g. microprocessors, radio tuners, audio ampli ers). Following this trend of system integration, this eventually leads to the integration of analog and d- ital components in one chip, resulting in mixed-signal ICs: digital components are required because signal processing is preferably done in the digital - main; analog components are required because physical signals are analog by nature. Mixed-signal ICs are already widespread in many applications (e. g. - dio, video); for the future, it is expected that this trend will continue, leading to a larger scale of integration.

Available in PDF, EPUB and Kindle. Book excerpt: A book is like a window that allows you to look into the world. The window is shaped by the author and that makes that every window presents a unique view of the world. This is certainly true for this book. It is shaped by the topics and the projects throughout my career. Even more so, this book re?ects my own style of working and thinking. That starts already in Chap. 2. When I joined Philips Research in 1979, many of my colleagues used little paper notebooks to keep track of the most used equations and other practical things. This notebook was the beginning for Chap. 2: a collection of topics that form the basis for much of the other chapters. Chapter2 is not intended to explain these topics, but to refresh your knowledge and help you when you need some basics to solve more complex issues. In the chapters discussing the fundamental processes of conversion, you will r- ognize my preoccupation with mathematics. I really enjoy ?nding an equation that properly describes the underlying mechanism. Nevertheless mathematics is not a goalonitsown:theequationshelptounderstandthewaythevariablesareconnected to the result. Real insight comes from understanding the physics and electronics. In the chapters on circuit design I have tried to reduce the circuit diagrams to the s- plest form, but not simpler. . . I do have private opinions on what works and what should not be applied.
Book Synopsis Reference-Free CMOS Pipeline Analog-to-Digital Converters by : Michael Figueiredo
Download or read book Reference-Free CMOS Pipeline Analog-to-Digital Converters written by Michael Figueiredo and published by Springer Science & Business Media. This book was released on 2012-08-24 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book shows that digitally assisted analog to digital converters are not the only way to cope with poor analog performance caused by technology scaling. It describes various analog design techniques that enhance the area and power efficiency without employing any type of digital calibration circuitry. These techniques consist of self-biasing for PVT enhancement, inverter-based design for improved speed/power ratio, gain-of-two obtained by voltage sum instead of charge redistribution, and current-mode reference shifting instead of voltage reference shifting. Together, these techniques allow enhancing the area and power efficiency of the main building blocks of a multiplying digital-to-analog converter (MDAC) based stage, namely, the flash quantizer, the amplifier, and the switched capacitor network of the MDAC. Complementing the theoretical analyses of the various techniques, a power efficient operational transconductance amplifier is implemented and experimentally characterized. Furthermore, a medium-low resolution reference-free high-speed time-interleaved pipeline ADC employing all mentioned design techniques and circuits is presented, implemented and experimentally characterized. This ADC is said to be reference-free because it precludes any reference voltage, therefore saving power and area, as reference circuits are not necessary. Experimental results demonstrate the potential of the techniques which enabled the implementation of area and power efficient circuits.

This book was released on 2023-01-12 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book proposes innovative circuit, architecture, and system solutions in deep-scaled CMOS and FinFET technologies, which address the challenges in maximizing the accuracy*speed/power of multi-GHz sample rate and bandwidth Analog-to-Digital Converters (ADC)s. A new holistic approach is introduced that first identifies the major error sources of a converter’ building blocks, and quantitatively analyzes their impact on the overall performance, establishing the fundamental circuit-imposed accuracy – speed – power limits. The analysis extends to the architecture level, by introducing a mathematical framework to estimate and compare the accuracy – speed – power limits of several ADC architectures and variants. To gain system-level insight, time-interleaving is covered in detail, and a framework is also introduced to compare key metrics of interleaver architectures quantitatively. The impact of technology is also considered by adding process effects from several deep-scaled CMOS technologies. The validity of the introduced analytical approach and the feasibility of the proposed concepts are demonstrated by four silicon prototype Integrated Circuits (IC)s, realized in ultra-deep-scaled CMOS and FinFET technologies. Introduces a new, holistic approach for the analysis and design of high-performance ADCs in deep-scaled CMOS technologies, from theoretical concepts to silicon bring-up and verification; Describes novel methods and techniques to push the accuracy – speed – power boundaries of multi-GHz ADCs, analyzing core and peripheral circuits’ trade-offs across the entire ADC chain; Supports the introduced analysis and design concepts by four state-of-the-art silicon prototype ICs, implemented in 28nm bulk CMOS and 16nm FinFET technologies; Provides a useful reference and a valuable tool for beginners as well as experienced ADC design engineers.
Book Synopsis Analog-Digital Converters for Industrial Applications Including an Introduction to Digital-Analog Converters by : Frank Ohnhäuser

This book was released on 2015-07-01 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers students and those new to the topic of analog-to-digital converters (ADCs) a broad introduction, before going into details of the state-of-the-art design techniques for SAR and DS converters, including the latest research topics, which are valuable for IC design engineers as well as users of ADCs in applications. The book then addresses important topics, such as correct connectivity of ADCs in an application, the verification, characterization and testing of ADCs that ensure high-quality end products. Analog-to-digital converters are the central element in any data processing system and regulation loops such as modems or electrical motor drives. They significantly affect the performance and resolution of a system or end product. System development engineers need to be familiar with the performance parameters of the converters and understand the advantages and disadvantages of the various architectures. Integrated circuit development engineers have to overcome the problem of achieving high performance and resolution with the lowest possible power dissipation, while the digital circuitry generates distortion in supply, ground and substrate. This book explains the connections and gives suggestions for obtaining the highest possible resolution. Novel trends are illustrated in the design of analog-to-digital converters based on successive approximation and the difficulties in the development of continuous-time delta-sigma modulators are also discussed.
