Abstract:
This report covers two ty temperature com pensation of crystal oscillators, the varicap method and the capacitor-diode method. Var ious approaches to using varicaps in different compensation schemes were investigated. One of the objects of investigating various compensation circuits is to find different compensation voltage versus temperature characteristics to determine if there is an optimum voltage versus temperature characteristic that can be obtained. A graphical approach to compensation using the capacitor-diode method is discussed. Curves of the predicted and actual curves of deltaf versus temperature are included to illustrate the accu racy of the graphical approach to compensation. The thermistor-resistor networks required for compensation are discussed along with the thermal transient problem. Aging data on temperature compensated crystal oscillators is also shown. Author
