Abstract

PURPOSE:To enable to make the adjustment of temperature compensation for the entire compensated temperature range effectively, by providing capacitors having greater and smaller temperature coefficient in series with each other and providing a capacitor having smaller temperature coefficient is parallel with the series circuit. CONSTITUTION:A series circuit of piezoelectric oscillator consisting of a quartz oscillator 36, thermister 31 producing a voltage depending on the ambient temperature, capacitor 33 and diode 34 and another series circuit of a capacitor 37 and a diode 38, are provided. Further, a capacitor 52 having smaller temperature coefficient is provided in series with a capacitor 51 having greater temperature coefficient, and a capacitor 53 having smaller temperature coefficient is provided parallel with this series circuit. Thus, the frequency-temperature compensation is made over the entire range of temperature compensation.
