Abstract
A voltage generator and a voltage generating method are provided. The voltage generator includes at least one first charge pump circuit, at least one second charge pump circuit, an oscillator, a passing circuit, and a voltage detector. The first charge pump circuit is configured to receive a clock signal to generate a first pump voltage. The second charge pump circuit is configured to receive the clock signal to generate a first pump voltage. The oscillator is configured to provide the clock signal. The passing circuit is configured to receive the clock signal, a power-on detection signal and an external command. The voltage detector is configured to receive an operation voltage, and generate the power-on detection signal by detecting the operation voltage. The passing circuit determines whether to transmit the clock signal to the second charge pump circuit or not to activate or deactivate the second charge pump circuit.
