A reference voltage generating circuit includes a constant current source circuit connected with a power supply voltage and configured to output a reference current to an output node based on the power supply voltage. A current-voltage converting circuit is connected the output node and generates a reference voltage to the output node based on the reference current. A first voltage adjusting circuit is connected with the output node and is configured to adjust dependence of the reference voltage on the power supply voltage in a positive direction. A second voltage adjusting circuit is connected with the output node and is configured to adjust dependence of the reference voltage on the power supply voltage in a negative direction.
