FREQUENCY TEMPERATURE COMPENSATION TECHNIQUES FOR QUARTZ CRYSTAL OSCILLATORS.
Abstract
This work involves development of circuit techniques for the frequency temperature compensation of three quartz crystal oscillator groups. Development of a linearized network approach has led to the generation of three separate computer programs. The three programs offer varying degrees of compensation, based on increasing circuit complexity. Successful application of these programs has been made in compensating the Group II oscillators. In conjunction with the programming effort, a preliminary investigation has been made to determine the effects of component tolerances on compensation. The Group II oscillator design was refined, and the improved features were incorporated in the final assembly of the oscillators. Circuit function and performance details are included in this report. First order compensation of these three oscillators indicates that the desired stability characteristics will be achieved. The oscillator aging experiment was initiated using eight oscillators housed in a stabilized-temperature enclosure. Compensation of these oscillators will be made as soon as initial aging trends are determined. Frequency adjustment studies were continued and resulted in a trimming method utilized which provides minimal effect on the degree of compensation.
