Abstract

A voltage generating circuit according to the present invention comprises a voltage converter which voltage-converts a reference voltage, and an output unit which impedance-converts the voltage outputted from the voltage converter. The voltage converter and the output unit each comprise a low-voltage-side power supply and a high-voltage-side power supply. A voltage level of the high-voltage-side power supply in the output unit is set to be higher than a voltage level of the high-voltage-side power supply in the voltage converter.
