Book excerpt: The expanding growth of mobile products and services has led to various wireless communication standards that employ different spectrum bands and protocols to provide data, voice or video communication services. Software defined radio and cognitive radio are emerging techniques that can dynamically integrate various standards to provide seamless global coverage, including global roaming across geographical regions, and interfacing with different wireless networks. In software defined radio and cognitive radio, one of the most critical RF blocks that need to exhibit frequency agility is the phase lock loop (PLL) frequency synthesizer. In order to access various standards, the frequency synthesizer needs to have wide frequency tuning range, fast tuning speed, and low phase noise and frequency spur. The traditional analog charge pump frequency synthesizer circuit design is becoming difficult due to the continuous down-scalings of transistor feature size and power supply voltage. The goal of this project was to develop an all digital phase locked loop (ADPLL) as the alternative solution technique in RF transceivers by taking advantage of digital circuitry’s characteristic features of good scalability, robustness against process variation and high noise margin. The targeted frequency bands for our ADPLL design included 880MHz-960MHz, 1.92GHz-2.17GHz, 2.3GHz-2.7GHz, 3.3GHz-3.8GHz and 5.15GHz-5.85GHz that are used by wireless communication standards such as GSM, UMTS, bluetooth, WiMAX and Wi-Fi etc. This project started with the system level model development for characterizing ADPLL phase noise, fractional spur and locking speed. Then an on-chip jitter detector and parameter adapter was designed for ADPLL to perform self-tuning and self-calibration to accomplish high frequency purity and fast frequency locking in each frequency band. A novel wide band DCO is presented for multi-band wireless application. The proposed wide band adaptive ADPLL was implemented in the IBM 0.13μm CMOS technology. The phase noise performance, the frequency locking speed as well as the tuning range of the digitally controlled oscillator was assessed and agrees well with the theoretical analysis.
Book Synopsis Digital Phase-locked Loops for Multi-GHz Clock Generation by : Volodymyr Kratyuk
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.

Book Synopsis A Multi-loop Calibration-free Phase-locked Loop (PLL) for Wideband Clock Generation by : Dihang Yang
Download or read book A Multi-loop Calibration-free Phase-locked Loop (PLL) for Wideband Clock Generation written by Dihang Yang and published by . This book was released on 2019 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a wide-band RF system, the RF channel is located within 50 MHz to 9 GHz. A high-frequency resolution phase-locked loop (PLL) with 100$\%$ tuning range oscillator is the core to generate the RF carrier frequency which covers such a wide range. The phase noise and spurs of the PLL are required to be low to avoid degrading RF system performance. A PLL applies $\Sigma \Delta$ modulation to increases its resolution and is known as a fractional-N PLL, but $\Sigma \Delta$ modulation introduces considerable quantization noise into the loop. The nonlinearity of the PLL also converts part of the noise into fractional-N spurs. Noise cancellation is usually applied to eliminate this quantization noise. Calibration, often with long settling time, is necessary to maintain cancellation efficiency. Power intensive calibration is also required to notch spurious tones. In this thesis, we first investigate the delay-locked loop (DLL) and attempt to use DLL to replace PLL as an RF frequency synthesizer. An LTI model of DLL is established, which indicates the limitation of DLL as a high-performance synthesizer. Then, the thesis focuses on PLL again. A calibration-free triple-loop PLL is introduced. The merits of heterodyne PLL are rediscovered, which applies a mixer in the loop to translate the VCO frequency to a low-frequency feedback signal. By implementing the harmonic mixing concept, the designed prototype effectively reduces the pulling risk of a traditional heterodyne PLL, allowing it to be integrated on a single chip. This PLL provides higher-order noise filtering and can naturally reduce fractional-N PLL noise and spurs. An analytical model for this PLL is also presented, which allows us to fully appreciate this PLL and optimize the loop design. After this, a sub-sampling PLL-based low-noise frequency extender is introduced, which increases the tuning range of an oscillator from 30$\%$ to 100$\%$, and requires only a small chip area. By combining the triple-loop PLL and the frequency extender, a synthesizer which can support a wideband radio system is achieved.

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.

Book Synopsis Improved Phase Detection for Digital Phase-locked Loops by : Amer Samarah
Download or read book Improved Phase Detection for Digital Phase-locked Loops written by Amer Samarah and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Digital PLLs (DPLLs) have emerged as reliable alternatives to analog PLLs since they are more robust in the presence of process variations and mismatch and do not need a large on-chip capacitor to realize a loop filter. However, a DPLL employs a time to-digital converter (TDC) to resolve the phase error in quantized steps which shows up as deterministic jitter in the output clock. Similarly, a DPLL tunes a digitally controlled-oscillator (DCO) in discrete frequency steps which adds an extra source of jitter. Furthermore, the quantized response of the DPLL may cause chaotic limit cycles in some configurations. This thesis presents innovations to make DPLLs suitable for a wide range of applications. First, a novel low-power TDC with 4 ps resolution, approximately an order of magnitude better than an inverter delay in the 0.13 μm CMOS technology, is enabled by employing a highly digital coarse-fine TDC with a calibrated coarse stage followed by a fine stochastic stage. On power-up, on-chip calibration algorithm based on a balanced mean code density test is used to minimize nonlinearities in the coarse TDC, reducing worst-case spurs from -54.4 dBc to -70.55 dBc at 1.995 GHz operation. The thesis also investigates dead-zone behavior in DPLLs caused by the quantization effect of the TDC. It results in chaotic limit cycle behavior; producing higher than expected in-band phase noise and strong spurious tones. To alleviate this problem, a noise-shaped offset is added to the phase error to keep the TDC active and away from the dead-zone. The proposed solution is demonstrated in a 0.13 μm CMOS prototype achieving consistent low in-band noise. A binary bang-bang phase detector (BBPD) is a commonly used alternative to the power hungry TDC. However, BBPD based DPLLs have limited frequency pull-in and capture range that are traded off for steady-state jitter performance. The thesis proposes an alternative to BBPD by using a multi-phase bang-bang detector (MPBBD). Also, the thesis presents a rigorous mathematical analysis of the cycle slipping behavior to quantify the pull-in and capture range as well as the locking time for DPLL with either BBPD or MPBBD. The final formula gives a useful insight into the effect of various loop parameters on the cycle slipping behavior. A DPLL architecture with a MPBBD is presented and implemented in 28 nm CMOS technology to improve the pull-in and capture range while not affecting the steady-state jitter performance.

Book Synopsis Deep Space Telecommunications Systems Engineering by : Joseph H. Yuen
Download or read book Deep Space Telecommunications Systems Engineering written by Joseph H. Yuen and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 615 pages. Available in PDF, EPUB and Kindle. Book excerpt: The challenge of communication in planetary exploration has been unusual. The guidance and control of spacecraft depend on reliable communication. Scientific data returned to earth are irreplaceable, or replaceable only at the cost of another mission. In deep space, communications propagation is good, relative to terrestrial communications, and there is an opportunity to press toward the mathematical limit of microwave communication. Yet the limits must be approached warily, with reliability as well as channel capacity in mind. Further, the effects of small changes in the earth's atmosphere and the interplanetary plasma have small but important effects on propagation time and hence on the measurement of distance. Advances are almost incredible. Communication capability measured in 18 bits per second at a given range rose by a factor of 10 in the 19 years from Explorer I of 1958 to Voyager of 1977. This improvement was attained through ingenious design based on the sort of penetrating analysis set forth in this book by engineers who took part in a highly detailed and amazingly successful pro gram. Careful observation and analysis have told us much about limitations on the accurate measurement of distance. It is not easy to get busy people to tell others clearly and in detail how they have solved important problems. Joseph H. Yuen and the other contribu tors to this book are to be commended for the time and care they have devoted to explicating one vital aspect of a great adventure of mankind.
