Abstract
A voltage supply circuit includes a step-down circuit configured to receive a power supply voltage, step down the power supply voltage to generate a step-down voltage having a constant value lower than a value of the power supply voltage, and a booster circuit configured to boost the step-down voltage to generate an output voltage, the output voltage having a value greater than the value of the power supply voltage.
