ABSTRACT:
A temperature compensating circuit for use with a crystal oscillator has a first bridge circuit for generating a first DC voltage with a linear functional temperature characteristic, a second bridge circuit for generating a second DC voltage with a quadratic functional temperature characteristic and a circuit for multiplying the first DC voltage and the second DC voltage so as to produce a DC voltage with a cubic functional characteristic. In this case, the DC voltage with the cubic functional characteristic is supplied to an oscillator circuit so as to compensate for variations in frequency of the crystal oscillator caused by temperature changes over a wide range thereof.
