Frequency Temperature Compensation Techniques for Quartz Crystal Oscillators
Abstract
This report discusses the results of investigation into the characteristics of temperature compensated crystal oscillators. A new compensation circuit using a diode switch is discussed and results are given on a number of experiments. Crystal and compensation networks are discussed to show the reasons for some types of non-linearities that occur in the delta f/f versus temperature characteristics of TCXO's. Voltage regulation and voltage regulator requirements are shown and results of one voltage regulator circuit are given. The effect of adjusting frequency is shown and possible methods of obtaining negligible effect on the compensation characteristics are examined. The initial design of a miniature TCXO is presented.
