This book was released on 2012-12-06 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 34 (thesis year 1989) a total of 13,377 theses titles from 26 Canadian and 184 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 34 reports theses submitted in 1989, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

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 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 Time to digital Converter for an All digital Phase locked Loop written by Sanjeet Sawant and published by . This book was released on 2017 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: A phase-locked loop (PLL) is a widely-used mixed-signal circuit that is used to create the precise clocks required on almost every integrated circuit. A PLL uses negative feedback to control an on-chip oscillator so that its frequency equals a multiple of a reference clock frequency provided from off-chip. The on-chip clock and the reference clock have a stable phase relationship. In recent years phase-locked loops have moved towards digital-intensive or all-digital designs due to advancements in CMOS technology which make these attractive in terms of area and power consumption. This project was to design and simulate a time-to-digital converter (TDC), which is a circuit used in an all-digital phase-locked loop. The TDC converts the phase difference between the on-chip clock and the reference clock into a digital code which is used to adjust the phase and frequency of the on-chip oscillator. Circuit schematics were designed for a time-to-digital converter in Cadence Virtuoso and simulated using the Spectre simulator in a 0.18um CMOS process. Simulations were performed to verify the performance across variations in process, supply voltage, and temperature.

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.

This book was released on 2016 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: A phase-locked loop is needed on nearly every integrated circuit to align the phase and frequency of the clock created by the on-chip oscillator to an external reference clock. This project was to design and simulate a programmable frequency divider in 0.18um CMOS for an all digital phase-locked loop integrated circuit. The frequency divider can provide one of four different output frequencies, based on the input control bits. Schematics for the programmable frequency divider were designed using Cadence Virtuoso, and simulations were performed using the Spectre simulator. Simulations were run for both typical and worst-case variations of process, supply voltage, and temperature.
Download or read book Digital Phase locked Loops for Multi GHz Clock Generation written by Volodymyr Kratyuk and published by . This book was released on 2007 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: A systematic design procedure for a second-order digital phase-locked loop with a linear phase detector is proposed. The design procedure is based on the analogy between a type-II second-order analog PLL and a digital PLL. A new digital PLL architecture featuring a linear phase detector which eliminates the noise-bandwidth tradeoff is presented. It employs a stochastic time-to-digital converter (STDC) and a high frequency delta-sigma dithering to achieve a wide PLL bandwidth and a low jitter. The measured results obtained from the prototype chip demonstrate a significant jitter improvement with the STDC.
