Abstract

A temperature compensated electronic timepiece comprises a time reference signal generator for generating a time reference signal and a temperature compensating device for compensating a change of the oscillating frequency of the time reference signal generator caused by any external temperature change. The temperature compensating device comprises a temperature detector having an element composed of two semiconductors of different respective conductivities (such as a transistor composed of P and N type semiconductors) which are joined to form a junction, or an element composed of a conductor and a semiconductor joined to form a junction. The voltage-current characteristics of the junction are changed when the external temperature exceeds a given temperature to deliver a digital signal whose state is reversed from an initial condition. The output signal from the temperature detector compensates any temperature change of the oscillating frequency of the time reference signal generator.
