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 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.

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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis covers the analysis, design and simulation of a low-power low-noise CMOS Phase-Locked Loop (PLL). Starting with the PLL basics, this thesis discussed the PLL loop dynamics and behavioral modeling. In this thesis, the detailed design and implementation of individual building blocks of the low-power low-noise PLL have been presented. In order to improve the PLL performance, several novel architectural solutions has been proposed. To reduce the effect of blind-zone and extend the detection range of Phase Frequency Detector (PFD), we proposed the Delayed-Input-Edge PFD (DIE-PFD) and the Delayed-Input-Pulse PFD (DIP-PFD) with improved performance. We also proposed a NMOS-switch high-swing cascode charge pump that significantly reduces the output current mismatches. Voltage Controlled Oscillator (VCO) consumes the most power and dominates the noise in the PLL. A differential ring VCO with 550MHz to 950MHz tuning range has been designed, with the power consumption of the VCO is 2.5mW and the phase noise -105.2dBc/Hz at 1MHz frequency offset. Finally, the entire PLL system has been simulated to observe the overall performance. With input reference clock frequency equal 50MHz, the PLL is able to produce an 800MHz output frequency with locking time 400ns. The power consumption of the PLL system is 2.6mW and the phase noise at 1MHz frequency offset is -119dBc/Hz. The designs are implemented using IBM 0.13æm CMOS technology.
