Title: Temperature compensation type quartz control oscillator
Inventor: SUGITA MITSUYUKI
IPC: H03H9/02
Filed: 1990-11-30
Abstract: PURPOSE:To attain the temperature compensation of an oscillating frequency, to simplify the circuit constitution and to reduce the cost by dividing an elec trode of one side of a quartz resonator into plural parts, connecting a thermistor to at least one of them, and connecting directly the remaining electrode divisions to a drive circuit. CONSTITUTION:When ambient temperature reaches 20 deg.C or over, the resistance of a thermistor 4a is very small, and when ambient temperature reaches 45 deg.C or over, the resistance of a thermistor 4b is gradually small. The capacitance among the electrodes 2a-2d is increased as the resistance of the thermistor 4b is decreased to compensate a frequency change in the quartz resonator 3 in the negative direction, Moreover, when the ambient temperature is 20 deg.C or less, the resistance of the thermistor 4a is gradually as temperature gets lower and the resistance of the thermistor 4b is very large. As the resistance of the thermistor 4a is increased, the capacitance among the electrodes 2a-2d is decreased and the frequency change in the quartz resonator 3 is compensated in the positive direction. Thus, the temperature is compensated with simple constitution.
