RESEARCH WORK FOR FREQUENCY TEMPERATURE COMPENSATION TECHNIQUES FOR QUARTZ CRYSTAL OSCILLATORS

Abstract

The different methods of frequency-temperature compensation (varicap, transistor and isolation stage, binistor, and capacitor-diode) are discussed. New techniques and approaches to compensation of crystal oscillators are presented, and mathematical analyses are developed for each. Empirical data is presented indicating the characteristics of each compensation method. A method of obtaining negligible effect of B volt age changes is presented. Several new approaches to voltage control networks are discussed, including a bridge voltage and current control network that is applicable to both the varicap and capacitor-diode methods. Aging data on four oscillators is presented which is a continuation of the aging tests started during the first quarter of this contract. The aging oscillators were temperature cycled and the original fre quency-temperature characteristics were compared to the characteristics obtained.
