Available in PDF, EPUB and Kindle. Book excerpt: A number of digital applications e.g. professional cameras, voice communication, video digitizers, data imaging and many more require low power, high speed, and high resolution analog to digital converters. But for high speed data communication systems with increased resolution and high sampling rates, different linear and nonlinear errors of ADCs come in picture which is a big challenge for design engineers to remove.A unique digital background calibration technique, a combination of signal dependent dithering with butterfly shuffler is proposed here for multi-bit, SHA-less 16-bit, 125 MS/s Pipelined ADC. The purpose of the research work was to integrate different stages of different sizes to achieve 16-bit error-free output at high sampling rate by using unique background calibration technique for SHA-less circuit. Because the achieved values of SNDR and SFDR are high with low power consumption, so this proposed ADC is suitable for high resolution applications like video communication. Without using sample and hold amplifier we saved power and reduced noise interference. Additional advantage of SHA removal is to use a smaller input sampling capacitor which increases ADC's drivability. A new timing diagram is also proposed here to resolve the sampling clock skew. The ultimate multi-bit front-end proposed here helped to save further power.The proposed comparator is able to avoid the kickback as compared to traditional comparators. For the initial multi-bit stage, a two-stage gain boosted amplifier is used to achieve high gain and to reduce the nonlinear gain errors. Because the non-idealities of Op-amp and capacitor mismatching errors, the ADC transfer function may achieve erroneous values by DNL errors, so the proposed technique is made capable to remove linear gain and offset errors and capacitor mismatching errors. Also the small signal linearity errors removed with the proposed architecture of 16-bit Pipelined ADC. Along with these advantages, high values of SNDR and SFDR has achieved, which is a top most indicator to distinguish the signal out from other noise and spurious frequencies.

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.

Download or read book Analog-Digital Converters for Industrial Applications Including an Introduction to Digital-Analog Converters written by Frank Ohnhäuser and published by Springer. This book was released on 2015-07-01 with total page 340 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.

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.

This book was released on 2021-12-30 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Document from the year 2021 in the subject Computer Science - Programming, grade: 10, Manipal University Jaipur, language: English, abstract: In this book, the primary research objective is to design a novel comparator to get rid-off reference-ladder circuit. The design of power efficient Flash ADC is investigated by utilizing a novel power optimized single-ended comparator. The proposed comparator generates inherent embedded threshold voltage. It uses the variable threshold voltage generation method for producing the reference voltage for the Flash ADC design. By employing optimized comparator, the Flash ADC achieves various benefits, as it does not require the necessity of a reference resistor ladder as well as front-end track and hold circuit. This reduces both layout area and power consumption and makes it appropriate for System-on-Chip (SoC) ADC implementation . The basic structure of the single-ended comparator is modified CMOS Inverter. The performance of modified CMOS Inverter circuit is compared with the static CMOS Inverter. To demonstrate the functionality of the new comparator, 4-bit and 6-bit Flash ADCs has been designed and simulated under the environment of Cadence and LTspice CAD tools. For both of the Flash ADCs, a comparative analysis is presented with previously published works on Flash ADCs. The secondary research objective is to propose a novel power reduction technique for high-speed Flash analog-to-digital converter, which not only reduces the power consumption in comparator but also examines the inactive comparators in the Flash ADC, thus inactive comparators get shutdown to save the unnecessary power consumption.This approach is based on two-step method of data conversion. By this method the total numbers of active comparators are reduced in comparison with the conventional Flash ADC. This feature of active comparators reduces the overall power consumption of the converter and the resultant architecture develops into power efficient Flash ADC architecture.

Book excerpt: This book discusses both architecture- and circuit-level design aspects of voltage-controlled-oscillator (VCO)-based analog-to-digital converters (ADCs), especially focusing on mitigation of VCO nonlinearity and the improvement of power efficiency. It shows readers how to develop power-efficient complementary-metal-oxide-semiconductor (CMOS) ADCs for applications such as LTE, 802.11n, and VDSL2+. The material covered can also be applied to other specifications and technologies. Design of Power-Efficient Highly Digital Analog-to-Digital Converters for Next-Generation Wireless Communication Systems begins with a general introduction to the applications of an ADC in communications systems and the basic concepts of VCO-based ADCs. The text addresses a wide range of converter architectures including open- and closed-loop technologies. Special attention is paid to the replacement of power-hungry analog blocks with VCO-based circuits and to the mitigation of VCO nonline arity. Various MATLAB®/Simulink® models are provided for important circuit nonidealities, allowing designers and researchers to determine the required specifications for the different building blocks that form the systematic integrated-circuit design procedure. Five different VCO-based ADC design examples are presented, introducing innovations at both architecture and circuit levels. Of these designs, the best power efficiency of a high-bandwidth oversampling ADC is achieved in a 40 nm CMOS demonstration. This book is essential reading material for engineers and researchers working on low-power-analog and mixed-signal design and may be used by instructors teaching advanced courses on the subject. It provides a clear overview and comparison of VCO-based ADC architectures and gives the reader insight into the most important circuit imperfections.
