【簡介】 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. 【目錄】 1 Introduction Part I Phase-Lock Basics 2 Linear Model and Loop Dynamics 3 Transient Response Part II System Perspectives 4 Frequency and Spectral Purity 5 Application Aspects Part III Building Circuits 6 PhaseDetector 7 Voltage-Controlled Oscillator 8 Frequency Divider Part IV PLL Architectures 9 Fractional-N PLL 10 Digital-Intensive PLL 11 Clock-and-Data Recovery PLL
