Описание: Presenting a phase noise modelling framework for CMOS ring oscillators, this book considers both linear and nonlinear operation. It indicates that fast rail-to-rail switching has to be achieved to minimize phase noise. In conventional design, the flicker noise in the bias circuit can potentially dominate the phase noise at low offset frequencies.
Описание: This is the first book to provide comprehensive coverage of the theory and practice of OPAs and related devices, including fiber optical parametric oscillators (OPOs). After introducing the field, the theory and techniques behind all types of fiber OPAs are covered starting from first principles - topics include the scalar and vector OPA theory; the nonlinear Schrodinger equation; OPO theory; and quantum noise figure of fiber OPAs. Challenges of making fiber OPAs practical for a number of applications are discussed, and a survey of the state-of-the-art in feasibility demonstrations and performance evaluations is provided. The capabilities and limitations of OPAs; the potential applications for OPAs and OPOs, and prospects for future developments in the field are discussed. Theoretical tools developed in this text can also be applied to other areas of nonlinear optics. This is a valuable resource for researchers, advanced practitioners, and graduate students in optoelectronics.
Описание: Delivering the best possible solution for phase noise and output power efficiency in oscillators This complete and thorough analysis of microwave oscillators investigates all aspects of design, with particular emphasis on operating conditions, choice of resonatoand transistors, phase noise, and output power. It covers both bipolar transistors and FETs. Following the authors' guidance, readers learn how to design microwave oscillators and VCOs that can be tuned over a very wide frequency range, yet have good phase noise, are low cost, and are small in size. All the essential topics in oscillator design and development are covered, including: * Device and resonator technology * Study of noise sources * Analysis methods * Design, calculation, and optimization methodologies * Practical design of single and coupled oscillators While most of the current literature in the field concentrates on classic design strategies based on measurements, simulation, and optimization of output power and phase noise, this text offers a unique approach that focuses on the complete understanding of the design process. The material demonstrates important design rules starting with the selection of best oscillator topology, choice of transistors, and complete phase noise analysis that leads to optimum performance of all relevant oscillator features. Also included are CMOS oscillators, which recently have become important in cellular applications. For readers interested in specialized applications and topics, a full chapter provides all the necessary references. The contents of the text fall into two major categories: * Chapters 1 through 9 deal with a very detailed and expanded single resonator oscillator, including a thorough treatment of both nonlinear analysis and phase noise * Chapters 10 and 11 use the knowledge obtained and apply it to multiple coupled oscillators (synchronized oscillators) This text is partially based on research sponsored by the Defense Advanced Research Projects Agency (DARPA) and the United States Army and conducted by Synergy Microwave Corporation. With the wealth of information provided for the analysis and practical design of single and synchronized low-noise microwave oscillators, it is recommended reading for all RF microwave engineers. In addition, the text's comprehensive, step-by-step approach makes it an excellent graduate-level textbook.
Описание: Since the 1960s digital signal processing (DSP) has been one of the most intensive fields of study in electronics. However, little has been produced specifically on linear non-adaptive time-variant digital filters. Presenting many examples demonstrating the application of the techniques, this text is dedicated to time-variant filtering and provides a complete introduction to the theory and practice of one of the sub-classes of time-varying digital systems, parametric digital filters and oscillators. It should be a useful resource for professional engineers, researchers and PhD students involved in digital signal and image processing, as well as postgraduate students on courses in computer, electrical, electronic and similar departments.

Описание: Covering the analysis and design of the most important integrated oscillator circuits, this book shows how to optimize them using the resonator`s high Q to achieve the minimum power consumption compatible with frequency stability and phase noise requirements.
Описание: Presenting a comprehensive account of oscillator phase noise and frequency stability, this practical text is both mathematically rigorous and accessible. An in-depth treatment of the noise mechanism is given, describing the oscillator as a physical system, and showing that simple general laws govern the stability of a large variety of oscillators differing in technology and frequency range. Inevitably, special attention is given to amplifiers, resonators, delay lines, feedback, and flicker (1/f) noise. The reverse engineering of oscillators based on phase-noise spectra is also covered, and end-of-chapter exercises are given. Uniquely, numerous practical examples are presented, including case studies taken from laboratory prototypes and commercial oscillators, which allow the oscillator internal design to be understood by analyzing its phase-noise spectrum. Based on tutorials given by the author at the Jet Propulsion Laboratory, international IEEE meetings, and in industry, this is a useful reference for academic researchers, industry practitioners, and graduate students in RF engineering and communications engineering.

Описание: Part of a series on circuits, this book contains 250-300 practical, ready-to-use circuit designs, with schematics and brief explanations of circuit operation. The original source for each circuit is listed in an appendix.
Описание: This book begins with an analysis of non-linear circuit design methods including spectral-domain analysis, time-domain analysis and the quasilinear method. It then moves on to discuss the operation and design principles of oscillators, including a section on the historical aspects of oscillator configurations. The stability of oscillators is next examined with discussions on the stability of multi-resonant circuits, the phase plane method and start-up and stability. Following this, the optimum design and circuit techniques are addressed, beginning with the empirical and analytic optimum design approaches, and moving on to the high-efficiency design technique. The next few chapters examine noise in oscillators including chapters on varactor and oscillator frequency tuning, CMOS voltage-controlled oscillators and wideband voltage-controlled oscillators. The book concludes with a chapter evaluating noise reduction techniques such as resonant circuit design technique, filtering technique and noise-shifting technique.
Описание: CMOS Fractional-N Synthesizers fits in the quest for small and cheap cellular transceiver solutions. The book is conceived as a manual for the design of fully integrated DeltaSigma fractional-N frequency synthesizers in CMOS with a focus on achieving a high spectral purity, i.e. low-phase-noise and high spurious suppression. Fractional-N design is elaborated from specification derivation up to architectural and building block level and down to circuit level. CMOS Fractional-N Synthesizers starts with a comprehensive introduction to general frequency synthesis. Different architectures and synthesizer building blocks are discussed with their relative importance on synthesizer specifications. The process of synthesizer specification derivation is illustrated with the DCS-1800 standard as a general test case. The book tackles the design of fractional-N synthesizers in CMOS on circuit level as well as system level. The circuit level focuses on high-speed prescaler design up to 12 GHz in CMOS and on fully integrated, low-phase-noise LC-VCO design. High-Q inductor integration and simulation in CMOS is elaborated and flicker noise minimization techniques are presented, ranging from bias point choice to noise filtering techniques. On a higher level, a systematic design strategy has been developed that trades off all noise contributions and fast dynamics for integrated capacitance (area). Moreover, a theoretical DeltaSigma phase noise analysis is presented, extended with a fast non-linear analysis method to accurately predict the influence of PLL non-linearities on the spectral purity of the DeltaSigma fractional-N frequency synthesizers. CMOS Fractional-N Synthesizers covers the total design flow of monolithic CMOS fractional-N synthesizers with high spectral purity while providing insight in the most critical issues of monolithic fractional-N synthesis. All material is experimentally verified with several CMOS implementations, with ultimately a monolithic CMOS &Dgr;&Sgr;-controlled fractional-N synthesizer, which was part of a CMOS DCS-1800 transceiver front-end. The book is essential reading for analog and RF design engineers and researchers in the field and it is also suitable as text book for an advanced course on the subject.
