STUDY OF CONSTRUCTION PRINCIPLES OF HIGH-STABLE INTEGRATED CRYSTAL OSCILLATORS WITH NON-LINEAR LIMITATION OF VOLTAGE APPLIED TO QUARTZ RESONATOR

There the risen dependence of effectiveness of variation transformation of properties of active part of oscillators under study into the frequency instability on the shape of current-voltage characteristics of active part has been brought out. The technique of construction of oscillators of type under study, which takes account of this dependence, has been developed. The manners of construction and computation of high-stable crystal oscillators with the active part to be not thermostated of integrated design, which allow to decrease the instability of frequency of like oscillators by one-two orders in comparison with the known analogues, have been developed. The computation methods, the practical circuits of crystal oscillators and of their separate functional units have been introduced at the Scientific-Production Union named after S.P. Pleshakov, at the Mius Scientific Design Office. The effectiveness is the increase of technicaland-economic characteristics of miniature crystal oscillators. The application fields are the aids of frequency stabilizationAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
