DOWNLOAD EBOOKPhase-Locked and Frequency-Feedback Systems: Principles and Techniques presents the operating principles and methods of design of phase-locked and frequency-feedback systems. This book is divided into 10 chapters that provide step-by-step design procedures and graphical aids, with illustrations bearing on real problems experienced in these systems. This work specifically tackles the application of these systems as FM demodulators with lowered thresholds. Chapters 1 and 2 deal briefly with the elements of linear systems, feedback theory, and noise, providing the minimum background for the material presented in the remainder of the text. Chapter 3 describes the characteristics of the major components that comprise the loops and the performance of the conventional and multi-loop FM demodulators. Chapters 4 to 7 present the basic describing equations and design for the FM feedback (FMFB) and phase-locked loop (PLL). These chapters further illustrate step-by-step design procedures with performance characteristics for low-threshold angle demodulation using typical design examples. Chapter 8 highlights the design principles, which are extended to the design of advanced demodulators featuring demodulation thresholds lower than those of the simple PLL or FMFB. Chapter 9 focuses on digital FM demodulation and PLL applications other than FM demodulation. Lastly, Chapter 10 presents the methods of testing and evaluating loop performance. Undergraduate and graduate level students, as well as practicing engineers, will find this book invaluable.

DOWNLOAD EBOOKPhase-Locked Loops Discover the essential materials for phase-locked loop circuit design, from fundamentals to practical design aspects A phase-locked loop (PLL) is a type of circuit with a range of important applications in telecommunications and computing. It generates an output signal with a controlled relationship to an input signal, such as an oscillator which matches the phases of input and output signals. This is a critical function in coherent communication systems, with the result that the theory and design of these circuits are essential to electronic communications of all kinds. Phase-Locked Loops: System Perspectives and Circuit Design Aspects provides a concise, accessible introduction to PLL design. It introduces readers to the role of PLLs in modern communication systems, the fundamental techniques of phase-lock circuitry, and the possible applications of PLLs in a wide variety of electronic communications contexts. The first book of its kind to incorporate modern architectures and to balance theoretical fundamentals with detailed design insights, this promises to be a must-own text for students and industry professionals. The book also features: Coverage of PLL basics with insightful analysis and examples tailored for circuit designers Applications of PLLs for both wireless and wireline systems Practical circuit design aspects for modern frequency generation, frequency modulation, and clock recovery systems Phase-Locked Loops is essential for graduate students and advanced undergraduates in integrated circuit design, as well researchers and engineers in electrical and computing subjects.

DOWNLOAD EBOOKHigh-performance digital systems use clocks to sequence operations and synchronize between functional units and between ICs. Clock frequencies and data rates have been increasing with each generation of processing technology and processor architecture. Phase locked-loops (PLLs) are widely used to generate well-timed on-chip clocks in high-performance digital systems. A PLL is a closed loop frequency system that locks the phase of an output signal to an input reference signal. PLL's are widely used in computer, radio, and telecommunications systems where it is necessary to stabilize a generated signal or to detect signals. The term "lock" refers to a constant or zero phase difference between two signals. The signal from the feedback path is compared to the input reference signal, until the two signals are locked. If the phase is unmatched, this is called the unlocked state, and the signal is sent to each component in the loop to correct the phase difference. These components consist of the Phase Frequency Detector (PFD), the charge pump (CP), the low pass filter (LPF), the voltage controlled oscillator (VCO) and divide by counter. The PFD detects any phase differences in and and then generates an error signal. According to that error signal the CP either increases or decreases the amount of charge to the LPF. This amount of charge either speeds up or slows down the VCO. The loop continues in this process until the phase difference between and is zero or constant--this is the locked mode. After the loop has attained a locked status, the loop still continues in the process but the output of each component is constant. The output signal has the same phase and/or frequency as .A divider can be used in the feedback path to synthesize a frequency different than that of the reference signal. The application I chose in designing the PLL was a frequency synthesizer. A frequency synthesizer generates a frequency that can have a different frequency from the original reference si.

DOWNLOAD EBOOKThis book develops for the first time a complete and connected nonlinear theory for the analog Phase-Locked Loop (PLL) which clarifies the obscure points of its complex non-linear behaviour. The book suggests new non-linear models for the PLL components and applies the averaging method to analyse PLL. The book presents the physical interpretation of the PLL operation, locates the difficulties presented by its operation and suggests solutions to overcome these problems. Finally it provides closed form expressions for all the important measures of the PLL and proposes new design criteria.

DOWNLOAD EBOOKIn this book, the authors outline detailed design methodology for fast frequency hopping synthesizers for RF and wireless communications applications. There is great emphasis on fractional-N delta-sigma based phase locked loops from specifications, system analysis and architecture planning to circuit design and silicon implementation. The developed techniques in the book can help in designing very low noise, high speed fractional-N frequency synthesizers.
