ABSTRACT:
A temperature-compensating voltage generator circuit for compensating the temperature characteristics of an electric device whose electrical characteristics vary in accordance with a change of the ambient temperature and can be changed or controlled by a control voltage. The temperature-compensating voltage generator circuit includes: a temperature-sensing device for generating an electric signal whose voltage level varies in accordance with a temperature change, and a discriminating device for discriminating the electric signal by using a predetermined reference voltage for generating output signals in accordance with the voltage level of the electric signal. The temperature-compensating voltage generator circuit also includes a distributing and combining device for distributing each of the output signals of the discriminating device into a plurality of distribution signals in accordance with a voltage ratio which is determined for each output signal and for generating a plurality of combined output signals by combining distribution signals distributed from each of the output signals of the discriminating device; and a coupling device for coupling the plurality of combined output signals of the distributing and combining device after inverting at least one of the plurality of combined output signals, and an output signal of the coupling device being used as a temperature-compensating voltage.
