ABSTRACT:
A circuit for generating a reference voltage includes a bandgap reference circuit that exhibits low temperature dependency of the output reference voltage. Since temperature dependencies of resistances thereof are appropriately controlled so that the temperature dependency of a load current flowing through divisional resistances is eliminated, it is possible to prevent the linearity of temperature dependency of the forward direction voltages of diodes from degrading. Accordingly, the temperature dependency of output is reduced.
