Abstract
A temperature compensating device for devices comprising semiconductors. The temperature compensating device comprises a temperature compensating circuit, such as a circuit including a diode, and a current control circuit which adjusts the quantity of the electric current flowing through the temperature compensating circuit. The temperature characteristic of the temperature compensating circuit is mutually compensatory with that of the output of the device comprising semiconductors. When the temperature characteristic of the output of said temperature compensating circuit differs from that of the output of such semiconductor device, the current control circuit causes a current which corresponds to the difference between the temperature coefficient of the compensating circuit and that of the semiconductor device to flow through the temperature compensating circuit, so that satisfactory temperature compensation can be accomplished.
