Abstract
A reference voltage generation circuit including: a first diode including a first conductive area; a second diode including a second conductive area that is larger than the first conductive area; a generation section configured to generate a reference voltage using a voltage based on the first diode and a voltage based on the second diode; and a first capacitor connected between a node of dividing resistors and an output of the generation section, the dividing resistors being connected between the output of the generation section and the second diode.
