发明名称 Reference voltage generating circuit and power supply device using the same
摘要 A reference voltage generating circuit for generating a reference voltage includes MOSFETs connected to each other. At least one of the MOSFETs includes a control gate and a floating gate that is made hole-rich or discharged by ultraviolet irradiation, and the reference voltage generating circuit is configured to output the difference between threshold voltages of a pair of the MOSFETs as the reference voltage.
