Abstract
Provided herein is a voltage generating circuit including: a negative voltage pump configured to generate a first negative voltage; and a negative voltage regulator configured to generate a second negative voltage using the first negative voltage and output the second negative voltage through an output terminal. The negative voltage regulator includes a first amplifier circuit configured to be controlled by a voltage of the output terminal, and a voltage booster configured to increase a voltage of the output terminal depending on an output voltage of the first amplifier circuit.
