Smart and Flexible Digital-to-Analog Converters by Georgi Radulov,Patrick Quinn,Hans Hegt,Arthur H.M. van Roermund Pdf

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.

Analog-Digital Converters for Industrial Applications Including an Introduction to Digital-Analog Converters by Frank Ohnhäuser Pdf

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.

Smart AD and DA Conversion by Pieter Harpe,Hans Hegt,Arthur H.M. van Roermund Pdf

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.

Interleaving Concepts for Digital-to-Analog Converters by Christian Schmidt Pdf

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.

Power-Efficient High-Speed Parallel-Sampling ADCs for Broadband Multi-carrier Systems by Yu Lin,Hans Hegt,Kostas Doris,Arthur H.M. van Roermund Pdf

This book addresses the challenges of designing high performance analog-to-digital converters (ADCs) based on the “smart data converters” concept, which implies context awareness, on-chip intelligence and adaptation. Readers will learn to exploit various information either a-priori or a-posteriori (obtained from devices, signals, applications or the ambient situations, etc.) for circuit and architecture optimization during the design phase or adaptation during operation, to enhance data converters performance, flexibility, robustness and power-efficiency. The authors focus on exploiting the a-priori knowledge of the system/application to develop enhancement techniques for ADCs, with particular emphasis on improving the power efficiency of high-speed and high-resolution ADCs for broadband multi-carrier systems.

Smart Adaptive Systems on Silicon by Maurizio Valle Pdf

Intelligent/smart systems have become common practice in many engineering applications. On the other hand, current low cost standard CMOS technology (and future foreseeable developments) makes available enormous potentialities. The next breakthrough will be the design and development of "smart adaptive systems on silicon" i.e. very power and highly size efficient complete systems (i.e. sensing, computing and "actuating" actions) with intelligence on board on a single silicon die. Smart adaptive systems on silicon will be able to "adapt" autonomously to the changing environment and will be able to implement "intelligent" behaviour and both perceptual and cognitive tasks. At last, they will communicate through wireless channels, they will be battery supplied or remote powered (via inductive coupling) and they will be ubiquitous in our every day life. Although many books deal with research and engineering topics (i.e. algorithms, technology, implementations, etc.) few of them try to bridge the gap between them and to address the issues related to feasibility, reliability and applications. Smart Adaptive Systems on Silicon, though not exhaustive, tries to fill this gap and to give answers mainly to the feasibility and reliability issues. Smart Adaptive Systems on Silicon mainly focuses on the analog and mixed mode implementation on silicon because this approach is amenable of achieving impressive energy and size efficiency. Moreover, analog systems can be more easily interfaced with sensing and actuating devices.

Integrated Analog-To-Digital and Digital-To-Analog Converters by Rudy J. van de Plassche Pdf

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.

Studies on Selected Topics in Radio Frequency Digital-to-Analog Converters by Mohammad Reza Sadeghifar Pdf

The network latency in fifth generation mobile technology (5G) will be around one millisecond which is much lower than in 4G technology. This significantly faster response time together with higher information capacity and ultra-reliable communication in 5G technology will pave the way for future innovations in a smart and connected society. This new 5G network should be built on a reasonable wireless infrastructure and 5G radio base-stations that can be vastly deployed. That is, while the electrical specification of a radio base-station in 5G should be met in order to have the network functioning, the size, weight and power consumption of the radio system should be optimized to be able to commercially deploy these radios in a huge network. As the number of antenna elements increases in massive multiple-input multiple-output based radios such as in 5G, designing true multi-band base-station radios, with efficient physical size, power consumption and cost in emerging cellular bands especially in mid-bands (frequencies up to 10~GHz), is becoming a challenge. This demands a hard integration of radio components; particularly the radio's digital application-specific integrated circuits (ASIC) with high-performance energy-efficient multi-band data converters. In this dissertation radio frequency digital-to-analog converter (RF DAC) and semi-digital finite-impulse response (FIR) filter digital-to-analog converter has been studied. Different techniques are used in these structures to improve the transmitter's overall performance. In the RF DAC part, a radio frequency digital-to-analog converter solution is presented, which is capable of monolithic integration into today's digital ASIC due to its digital-in-nature architecture, while fulfills the stringent requirements of cellular network radio base station linearity and bandwidth. A voltage-mode conversion method is used as output stage, and configurable mixing logic is employed in the data path to create a higher frequency lobe and utilize the output signal in the first or the second Nyquist zone and hence achieving output frequencies up to the sample rate. In the semi-digital FIR part, optimization problem formulation for semi-digital FIR digital-to-analog converter is investigated. Magnitude and energy metrics with variable coefficient precision are defined for cascaded digital Sigma-Delta modulators, semi-digital FIR filter, and Sinc roll-off frequency response of the DAC. A set of analog metrics as hardware cost is also defined to be included in semi-digital FIR DAC optimization problem formulation. It is shown that hardware cost of the semi-digital FIR DAC, can be reduced by introducing flexible coefficient precision in filter optimization while the semi-digital FIR DAC is not over-designed either. Different use cases are selected to demonstrate the optimization problem formulations. A combination of magnitude metric, energy metric, coefficient precision and analog metric are used in different use cases of the optimization problem formulation and solved to find out the optimum set of analog FIR taps. Moreover, a direct digital-to-RF converter (DRFC) is presented in this thesis where a semi-digital FIR topology utilizes voltage-mode RF DAC cells to synthesize spectrally clean signals at RF frequencies. Due to its digital-in-nature design, the DRFC benefits from technology scaling and can be monolithically integrated into advance digital VLSI systems. A fourth-order single-bit quantizer bandpass digital Sigma-Delta modulator is used preceding the DRFC, resulting in a high in-band signal-to-noise ratio (SNR). The out-of-band spectrally-shaped quantization noise is attenuated by an embedded semi-digital FIR filter. The RF output frequencies are synthesized by a configurable voltage-mode RF DAC solution with a high linearity performance. A compensation technique to cancel the code-dependent supply current variation in voltage-mode RF DAC for radio frequency direct digital frequency synthesizer is also presented in this dissertation and is studied analytically. The voltage-mode RF DAC and the compensation technique are mathematically modeled and system-level simulation is performed to support the analytical discussion.

Robust Sigma Delta Converters by Robert H.M. van Veldhoven,Arthur H.M. van Roermund Pdf

Sigma Delta converters are a very popular choice for the A/D converter in multi-standard, mobile and cellular receivers. Key A/D converter specifications are high dynamic range, robustness, scalability, low-power and low EMI. Robust Sigma Delta Converters presents a requirement derivation of a Sigma Delta modulator applied in a receiver for cellular and connectivity, and shows trade-offs between RF and ADC. The book proposes to categorize these requirements in 5 quality indicators which can be used to qualify a system, namely accuracy, robustness, flexibility, efficiency and emission. In the book these quality indicators are used to categorize Sigma Delta converter theory. A few highlights on each of these quality indicators are; Quality indicators: provide a means to quantify system quality. Accuracy: introduction of new Sigma Delta Modulator architectures. Robustness: a significant extension on clock jitter theory based on phase and error amplitude error models. Extension of the theory describing aliasing in Sigma Delta converters for different types of DACs in the feedback loop. Flexibility: introduction of a Sigma Delta converter bandwidth scaling theory leading to very flexible Sigma Delta converters. Efficiency: introduction of new Figure-of-Merits which better reflect performance-power trade-offs. Emission: analysis of Sigma Delta modulators on emission is not part of the book The quality indicators also reveal that, to exploit nowadays advanced IC technologies, things should be done as much as possible digital up to a limit where system optimization allows reducing system margins. At the end of the book Sigma Delta converter implementations are shown which are digitized on application-, architecture-, circuit- and layout-level. Robust Sigma Delta Converters is written under the assumption that the reader has some background in receivers and in A/D conversion.

Analog-to-Digital Conversion by Marcel J.M. Pelgrom Pdf

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.
