Download or read book A New Programmable Low Noise All Digital Phase locked Loop Architecture written by Justin L. Gaither and published by . This book was released on 2005 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the electronics industry today almost without exception there are phase-locked loops (PLL) implemented within each system and often within each integrated circuit (IC). In fact, most PLL's are implemented monolithically within ICs without any or with very few external components. Additionally, most are implemented as Analog PLL's utilizing only a digital phase detector. This is also evident in the majority of recent publications which focus on PLL structures with on-chip voltage controlled oscillators using charge pumps and ring or LC oscillators. However, the problem with most on-chip VCO's is that they are far noisier than the external crystal types. The noise in the integrated oscillators forces designers to use larger loop bandwidths than would be required with less noisy VCO's; subsequently they have poor noise filtering capabilities. Additionally, analog PLL's are usually fixed in nature. Loop components such as charge-pumps and loop filters are implemented as analog components with little or no flexibility. The focus of this thesis is the design and implementation of a very low cost, low noise Programmable All Digital PLL (ADPLL) which utilizes a low cost digital to analog converter (DAC), a voltage controlled crystal oscillator (VCXO), and a field programmable gate array (FPGA). The use of FPGA technology for digital design implementation is universal in the industry and provides benefits far beyond the implementation of ADPLL's. In fact, in almost every system today, an FPGA already exists. Therefore, the inclusion of a DPLL within existing system components would be at little or no cost. The implementation of the PLL digitally not only allows us to implement it within an FPGA, but also allows us to adapt and configure the PLL for many applications and tune it for best performance. Digital circuits also have increased noise margin and are not affected by the same noise issues associated with Analog PLL's such as temperature, voltage and noise coupled from other signals or circuits. The DPLL developed is flexible and can be configured to operate as a clock and data recovery circuit (CDR), clock multiplier, clock synthesizer, or noise filtering PLL. Using an external VCXO provides a very low noise basis for the PLL and such that we can implement very low bandwidths without sacrificing the quality of its output. In this thesis we will present the theory, architecture, design, hardware and implementation of the ADPLL in addition to the results of the testing of the prototype ADPLL that was built.

Download or read book Phase Locked Loops for Wireless Communications written by Donald R. Stephens and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phase-Locked Loops for Wireless Communications: Digitial, Analog and Optical Implementations, Second Edition presents a complete tutorial of phase-locked loops from analog implementations to digital and optical designs. The text establishes a thorough foundation of continuous-time analysis techniques and maintains a consistent notation as discrete-time and non-uniform sampling are presented. New to this edition is a complete treatment of charge pumps and the complementary sequential phase detector. Another important change is the increased use of MATLAB®, implemented to provide more familiar graphics and reader-derived phase-locked loop simulation. Frequency synthesizers and digital divider analysis/techniques have been added to this second edition. Perhaps most distinctive is the chapter on optical phase-locked loops that begins with sections discussing components such as lasers and photodetectors and finishing with homodyne and heterodyne loops. Starting with a historical overview, presenting analog, digital, and optical PLLs, discussing phase noise analysis, and including circuits/algorithms for data synchronization, this volume contains new techniques being used in this field. Highlights of the Second Edition: Development of phase-locked loops from analog to digital and optical, with consistent notation throughout; Expanded coverage of the loop filters used to design second and third order PLLs; Design examples on delay-locked loops used to synchronize circuits on CPUs and ASICS; New material on digital dividers that dominate a frequency synthesizer's noise floor. Techniques to analytically estimate the phase noise of a divider; Presentation of optical phase-locked loops with primers on the optical components and fundamentals of optical mixing; Section on automatic frequency control to provide frequency-locking of the lasers instead of phase-locking; Presentation of charge pumps, counters, and delay-locked loops. The Second Edition includes the essential topics needed by wireless, optics, and the traditional phase-locked loop specialists to design circuits and software algorithms. All of the material has been updated throughout the book.
Download or read book Frequency Synthesis Of All Digital Phase Locked Loop written by Saravanakumar Subramanian and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: All Digital Phase Locked Loops (ADPLLs) have become more attractive because they yield better testability, programmability, stability, and portability over different processes and the ADPLLs can reduce the system turn around time. Phase-locked loop mechanisms may be implemented as either analog or digital circuits. Both implementations use the same basic structure. The implemented ADPLL has two operation modes which are frequency acquisition mode and phase acquisition mode. In frequency acquisition mode, the ADPLL achieves a fast frequency locking via the proposed feed-forward compensation algorithm. In phase acquisition mode, the ADPLL achieves a finer phase locking.
Download or read book Phase Locked Loops for Wireless Communications written by Donald R. Stephens and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended for the graduate or advanced undergraduate engineer. The primary motivation for writing the text was to present a complete tutorial of phase-locked loops with a consistent notation. As such, it can serve as a textbook in formal classroom instruction, or as a self-study guide for the practicing engineer. A former colleague, Kevin Kreitzer, had suggested that I write a text, with an emphasis on digital phase-locked loops. As modem designers, we were continually receiving requests from other engineers asking for a definitive reference on digital phase-locked loops. There are several good papers in the literature, but there was not a good textbook for either classroom or self-paced study. From my own experience in designing low phase noise synthesizers, I also knew that third-order analog loop design was omitted from most texts. With those requirements, the material in the text seemed to flow naturally. Chapter 1 is the early history of phase-locked loops. I believe that historical knowledge can provide insight to the development and progress of a field, and phase-locked loops are no exception. As discussed in Chapter 1, consumer electronics (color television) prompted a rapid growth in phase-locked loop theory and applications, much like the wireless communications growth today. xiv Preface Although all-analog phase-locked loops are becoming rare, the continuous time nature of analog loops allows a good introduction to phase-locked loop theory.

This book was released on 2006-09-22 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new and innovative paradigm for RF frequency synthesis and wireless transmitter design Learn the techniques for designing and implementing an all-digital RF frequency synthesizer. In contrast to traditional RF techniques, this innovative book sets forth digitally intensive design techniques that lead the way to the development of low-cost, low-power, and highly integrated circuits for RF functions in deep submicron CMOS processes. Furthermore, the authors demonstrate how the architecture enables readers to integrate an RF front-end with the digital back-end onto a single silicon die using standard ASIC design flow. Taking a bottom-up approach that progressively builds skills and knowledge, the book begins with an introduction to basic concepts of frequency synthesis and then guides the reader through an all-digital RF frequency synthesizer design: Chapter 2 presents a digitally controlled oscillator (DCO), which is the foundation of a novel architecture, and introduces a time-domain model used for analysis and VHDL simulation Chapter 3 adds a hierarchical layer of arithmetic abstraction to the DCO that makes it easier to operate algorithmically Chapter 4 builds a phase correction mechanism around the DCO such that the system's frequency drift or wander performance matches that of the stable external frequency reference Chapter 5 presents an application of the all-digital RF synthesizer Chapter 6 describes the behavioral modeling and simulation methodology used in design The final chapter presents the implementation of a full transmitter and experimental results. The novel ideas presented here have been implemented and proven in two high-volume, commercial single-chip radios developed at Texas Instruments: Bluetooth and GSM. While the focus of the book is on RF frequency synthesizer design, the techniques can be applied to the design of other digitally assisted analog circuits as well. This book is a must-read for students and engineers who want to learn a new paradigm for RF frequency synthesis and wireless transmitter design using digitally intensive design techniques.

This book was released on 2015-01-29 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book reports two approaches of implementation of the essential components of a Digital Phase Locked Loop based system for dealing with wireless channels showing Nakagami-m fading. It is mostly observed in mobile communication. In the first approach, the structure of a Digital phase locked loop (DPLL) based on Zero Crossing (ZC) algorithm is proposed. In a modified form, the structure of a DPLL based systems for dealing with Nakagami-m fading based on Least Square Polynomial Fitting Filter is proposed, which operates at moderate sampling frequencies. A sixth order Least Square Polynomial Fitting (LSPF) block and Roots Approximator (RA) for better phase-frequency detection has been implemented as a replacement of Phase Frequency Detector (PFD) and Loop Filter (LF) of a traditional DPLL, which has helped to attain optimum performance of DPLL. The results of simulation of the proposed DPLL with Nakagami-m fading and QPSK modulation is discussed in detail which shows that the proposed method provides better performance than existing systems of similar type.
