摘要： A reference voltage generator circuit includes a band gap reference voltage circuit that generates a predetermined reference voltage, and a first correction current generator circuit that generates a first correction current in response to change in temperature. The first correction current generator circuit generates a plurality of voltage peaks in response to the change in temperature in the output voltage of the reference voltage generator circuit by injecting the first correction current into the band gap reference voltage circuit, and output voltage characteristics configuring each of the plurality of voltage peaks are made such that the output voltage varies continuously with respect to the change in temperature. The first correction current generator circuit includes a temperature setting circuit that can change the plurality of temperatures corresponding to each of the plurality of voltage peaks.
