Document Type and Number:
Japanese Patent JPS6362924
Kind Code:
B2
Abstract:
A temperature-compensating voltage generator circuit for compensating the temperature characteristics of an electric device whose electrical characteristics vary in accordance with the change of the ambient temperature and can be changed or controlled by a control voltage comprises: temperature-sensing means (1) for generating an electric signal whose voltage level varies in accordance with a temperature change; discriminating means (2) for discriminating the electric signal by using a predetermined reference voltage and for generating intermediate signals (e,, e2) in accordance with the voltage level of the electric signal; and combining means (3) for combining the intermediate signals in accordance with a selected voltage ratio, thereby to provide an output signal (e4) for use as a temperature-compensating voltage. Such a generator can allow independent compensation of temperature characteristics at high and low temperatures.
