Abstract
A voltage generating device includes a clock signal generator, a voltage regulator and a pump circuit. The clock signal generator generates a clock signal according to an enable signal. The voltage regulator generates and adjusts a first voltage according to a reference voltage and the enable signal. The pump circuit receives the clock signal, the first voltage and a second voltage, wherein the pump circuit performs a voltage pump operation to generate an output voltage based on the clock signal according to the first voltage and the second voltage. The output voltage equals to a summation of the first voltage and the second voltage.
