IPC: H03B5/32
Filed: 1989-09-27
Abstract: PURPOSE:To facilitate temperature compensation with high accuracy by interposing a capacitor of a small capacitance to suppress frequency fluctuation due to a resistive component change of a temperature compensation circuit between a collector of an oscillating transistor(TR) and a reference potential point in a Colpitz type crystal oscillator. CONSTITUTION:A small capacity capacitor 31 for compensation is interposed between a collector of transistor of a oscillating circuit and a reference potential. A variable series resistor connected in series with a crystal resonator 1 in a Colpitz type oscillation circuit and its resistance is varied, then the changing direction and the changing quantity of the oscillating frequency are changed in response to the capacitance of the compensation capacitor 31. That is, when the capacitance of the capacitor 31 is small, the oscillator is in a negative characteristic with respect to the increase in the series resistance and when the capacitance of the capacitor 31 is large, the oscillator is in a positive characteristic with respect to the increase in the series resistance conversely. Thus, the capacitor 31 of a proper value is selected to keep a nearly constant frequency with respect to a change in the series resistance. Thus, highly accurate temperature compensation is attained, the productivity of the oscillator is remarkably improved and the cost is reduced.
