Download or read book Understanding Quartz Crystals and Oscillators written by Ramon M. Cerda and published by Artech House. This book was released on 2014-05-01 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quartz, unique in its chemical, electrical, mechanical, and thermal properties, is used as a frequency control element in applications where stability of frequency is an absolute necessity. Without crystal controlled transmission, radio and television would not be possible in their present form. The quartz crystals allow the individual channels in communication systems to be spaced closer together to make better use of one of most precious resources -- wireless bandwidth. This book describes the characteristics of the art of crystal oscillator design, including how to specify and select crystal oscillators. While presenting various varieties of crystal oscillators, this resource also provides you with useful MathCad and Genesys simulations.

Book excerpt: The purpose of the program was to compile a quartz crystal oscillator design handbook to facilitate and systematize the design of quartz crystal oscillators, to eliminate crystal unit misapplications, to reduce design time and costs, and to increase the reliability of operation. The handbook is specifically directed at the wide operating temperature range, medium stability crystal oscillator prevalent in many types of communications equipment, although the basic design principles also apply to temperature controlled oscillators. In addition, the program was concerned with obtaining oscillator performance data for inclusion in the handbook.

Available in PDF, EPUB and Kindle. Book excerpt: The object of this handbook is to assemble a set of design methods for crystal oscillators in the frequency range of 1 KC to 200 MC with the aim of facilitating design, eliminating crystal unit misapplications, and reducing design costs. The handbook is not directed at the design of ultra-stable crystal oscillators, but rather at the non-temperature controlled, medium frequency stability oscillator commonly in use in many types of communications equipment. The handbook contains discussions of: (1) The electrical characteristics of crystal units, condition of usage, and methods of measurement. (2) Characteristics of tube and transistor amplifiers. (3) Characteristics of impedance transforming networks. (4) Detailed design information on series resonance and anti-resonance oscillators. (5) Design examples together with experimental evaluation data covering most of the 1 KC to 200 MC range. (Author).

This book was released on 1964 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this project is to evolve a practical approach to the temperature compensation of quartz crystal oscillators. The study will be concentrated on a nominal frequency of five megacycles, but will be generally applicable to AT cut quartz crystals of from 1 to 20 megacycles. The use of graphical analysis for TCXO design is discussed. The results of this investigation show that a graphical analysis will not be useable for very accurate compensation because of resolution and parameters that cannot be taken into account with graphs. The techniques for determining compensation networks are discussed. A new technique is described where diodes are used in conjunction with thermistor-resistor networks. The 5 x 10 to the minus 8th power, Group III, TCXO's are discussed. Results of the first compensation attempts are given. The compensation networks and techniques used are presented. (Author).

This book was released on 2012-12-06 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crystal oscillators have been in use now for well over SO years-one of the first was built by W. G. Cady in 1921. Today, millions of them are made every year, covering a range of frequencies from a few Kilohertz to several hundred Mega hertz and a range of stabilities from a fraction of one percent to a few parts in ten to the thirteenth, with most of them, by far, still in the range of several tens of parts per million.Their major application has long been the stabilization of fre quencies in transmitters and receivers, and indeed, the utilization of the frequency spectrum would be in utter chaos, and the communication systems as we know them today unthinkable,'without crystal oscillators. With the need to accommodate ever increasing numbers of users in a limited spectrum space, this traditional application will continue to grow for the fore seeable future, and ever tighter tolerances will have to be met by an ever larger percentage of these devices.

Download or read book Low Power Crystal and MEMS Oscillators written by Eric Vittoz and published by Springer Science & Business Media. This book was released on 2010-08-03 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electronic oscillators using an electromechanical device as a frequency reference are irreplaceable components of systems-on-chip for time-keeping, carrier frequency generation and digital clock generation. With their excellent frequency stability and very large quality factor Q, quartz crystal resonators have been the dominant solution for more than 70 years. But new possibilities are now offered by micro-electro-mechanical (MEM) resonators, that have a qualitatively identical equivalent electrical circuit. Low-Power Crystal and MEMS Oscillators concentrates on the analysis and design of the most important schemes of integrated oscillator circuits. It explains how these circuits can be optimized by best exploiting the very high Q of the resonator to achieve the minimum power consumption compatible with the requirements on frequency stability and phase noise. The author has 40 years of experience in designing very low-power, high-performance quartz oscillators for watches and other battery operated systems and has accumulated most of the material during this period. Some additional original material related to phase noise has been added. The explanations are mainly supported by analytical developments, whereas computer simulation is limited to numerical examples. The main part is dedicated to the most important Pierce circuit, with a full design procedure illustrated by examples. Symmetrical circuits that became popular for modern telecommunication systems are analyzed in a last chapter.
Download or read book Study of Short Term Stability of Crystal Oscillators written by LESTER. SAPORTA and published by . This book was released on 1961 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study is described of the effects of noise on the r.m.s. frequency deviation of an oscillator. Several models are assumed. In one case the noise and signal are linearly added and the assumption is made that the noise does not enter the feedback loop o the oscillator. It is shown that this predicts an inverse first power variation of the r.m.s. frequency deviation with respect to the integration time inherent in the frequency measurement. In other models, the noise is included in the feedback loop and results in an inverse one-half power variation. Evidence is adduced to indicate that both effects take place in practical oscillators and some estimates of the magnitude of these effects are made. (Author).
