Synopsis Analysis and Design of Quadrature Oscillators by : Luis B. Oliveira
Modern RF receivers and transmitters require quadrature oscillators with accurate quadrature and low phase-noise. Existing literature is dedicated mainly to single oscillators, and is strongly biased towards LC oscillators. This book is devoted to quadrature oscillatorsand presents adetailed comparative study ofLC and RCosc- lators, both at architectural and at circuit levels. It is shown that in cross-coupled RC oscillators both the quadrature error and phase-noise are reduced, whereas in LC - cillators the coupling decreases the quadrature error, but increases the phase-noise. Thus, quadrature RC oscillators can be a practical alternative to LC oscillators, - pecially when area and cost are to be minimized. The main topics of the book are: cross-coupled LC quasi-sinusoidal oscillators, cross-coupled RC relaxation oscillators, a quadrature RC oscillator-mixer, and t- integrator oscillators. The effect of mismatches on the phase-error and the pha- noise are thoroughly investigated. The book includes many experimental results, obtained from different integrated circuit prototypes, in the GHz range. A structured design approach is followed: a technology independent study, with ideal blocks, is performed initially, and then the circuit level design is addressed. This book can be used in advanced courses on RF circuit design. In addition to post-graduate students and lecturers, this book will be of interest to design engineers and researchers in this area.

Synopsis Foundations of Oscillator Circuit Design by : Guillermo Gonzalez
Oscillators are an important component in today's RF and microwave systems, and practitioners in the field need to know how to design oscillators for stability and top performance. Offering engineers broader coverage than other oscillator design books on the market, this comprehensive resource considers the complete frequency range, from low-frequency audio oscillators to more complex oscillators found at the RF and microwave frequencies. Packed with over 1,200 equations, the book gives professionals a thorough understanding of the principles and practice of oscillator circuit design and emphasizes the use of time-saving CAD (computer aided design) simulation techniques. From the theory and characteristics of oscillators, to the design of a wide variety of oscillators (including tuned-circuit, crystal, negative-resistance, and relaxation oscillators), this unique book is a one-stop reference practitioners can turn to again and again when working on their challenging projects in this field.

Synopsis A High Frequency Current-controlled Oscillator for Integrated Circuits [microform] by : Erasto M. (Erasto Muganyizi) Kashoro
A sinusoidal RC-oscillator built around a current-controlled current amplifier is presented. Three main problems associated with RC-oscillators, namely poor frequency performance, amplitude drift and a large temperature coefficient of frequency, are addressed, and ways of solving these problems are discussed. The large temperature sensitivities typical of active RC networks were reduced by eliminating the active portion of the drift. This was accomplished through the use of thermally balanced amplifiers whose operation is independent of transistor parameters. It is shown that the frequency performance of a typical Wien-oscillator is significantly improved when fast current amplifiers are used to replace commercial voltage operational amplifiers. The generation of a sinusoidal signal directly from the oscillator gave a lower total harmonic distortion (THD) than in the more popular approaches using multivibrators and shaping networks. A new method for stabilizing the amplitude of oscillation has been developed. It employs a high frequency rectifier and a comparator in a feedback loop which is connected to the RC network of the oscillator through an active current divider. The feedback loop regulates the current in the RC network and thereby stabilizes the amplitude. A linear automatic gain control (AGC) model was developed and the stability requirements for the amplitude control loop were studied. Frequency stabilization for oscillators is a very difficult task. Most communication systems requiring tight frequency stability incorporate frequency synthesizers which have a large IC count and are expensive.

Synopsis The Designer's Guide to High-Purity Oscillators by : Emad Eldin Hegazi
try to predict it using mathematical expressions. His heuristic model without mathematical proof is almost universally accepted. However, it entails a c- cuit specific noise factor that is not known a priori and so is not predictive. In this work, we attempt to address the topic of oscillator design from a diff- ent perspective. By introducing a new paradigm that accurately captures the subtleties of phase noise we try to answer the question: 'why do oscillators behave in a particular way?' and 'what can be done to build an optimum design?' It is also hoped that the paradigm is useful in other areas of circuit design such as frequency synthesis and clock recovery. In Chapter 1, a general introduction and motivation to the subject is presented. Chapter 2 summarizes the fundamentals of phase noise and timing jitter and discusses earlier works on oscillator's phase noise analysis. Chapter 3 and Chapter 4 analyze the physical mechanisms behind phase noise generation in current-biased and Colpitts oscillators. Chapter 5 discusses design trade-offs and new techniques in LC oscillator design that allows optimal design. Chapter 6 and Chapter 7 discuss a topic that is typically ignored in oscillator design. That is flicker noise in LC oscillators. Finally, Chapter 8 is dedicated to the complete analysis of the role of varactors both in tuning and AM-FM noise conversion.
