Abstract
a reference voltage generating circuit that includes a bandgap reference voltage generating circuit main body () configured to generate a substantially constant reference voltage at room temperature, a high temperature correction circuit () configured to increase a reference voltage generated by the reference voltage generating circuit main body at a high temperature by supplying a high temperature correction current that increases as the temperature increases to the resistor, a low temperature correction circuit () configured to increase a reference voltage generated by the reference voltage generating circuit main body at a low temperature by supplying a low temperature correction current that increases as the temperature decreases to the resistor, and a bias circuit () configured to generate a bias voltage according to the temperature, so as to control the high temperature correction current and the low temperature correction current at the same time.
