Reference voltage generator

A reference voltage generator is provided to maximize the accuracy and the reliability of the operation at circuit and to reduce the circuit complexity by generating the reference voltage having no concern with the temperature change. A reference voltage generator comprises the first referent voltage generating part and the current compensation part. The first referent voltage generating part is provided with the power source(10) voltage and produces the first reference voltage. The current compensation part generates the compensating current having the temperature - current property curve opposite to the temperature - voltage characteristic curve to the first reference voltage generated from the first referent voltage generating part. The first referent voltage generating part receives the compensating current and corrects the temperature - voltage characteristic curve to the first reference voltage. The first referent voltage generating part outputs the voltage deviation reduced according to the temperature change.
