ABSTRACT:
A circuit for generating a constant voltage, free of dependence on temperature changes, by adding a voltage having positive temperature dependence to a voltage having negative temperature dependence. A current generation circuit for generating a current having positive temperature dependence is connected with an element for converting this current to a voltage by way of a proportional current supply circuit, for example, a current mirror circuit.
