A electric Voltage corresponding to the environmental temperature can be obtained in a MOS transistor circuit operating in the range of exponential function. By use of this circuit as a temperature sensor, frequency variation of quartz vibrators due to the ambient temperature has been compensated successfully. According to this resuIt, it has been proved that the frequency can be stabilized within ± 1 ppm in a temperature range from 0°through 50℃, and a frequency compensating system for wrist watches more precise and more stable as compared with that used so far has been obtained.
