Abstract
A power providing circuit and a power providing method are provided. The power providing circuit includes at least one first charge pump circuit, at least one second charge pump circuit, a first control circuit, a signal latch, and a voltage detector. The first charge pump circuit is configured to receive a first clock to generate a first pump voltage. The second charge pump circuit is configured to receive the first clock to generate the first pump voltage. The first control circuit is configured to provide the first clock to the first charge pump circuit and the at second charge pump circuit according to a power-on detection signal. The signal latch is coupled to the second charge pump circuit. The voltage detector is configured to receive an operation voltage and generate the power-on detection signal by detecting the operation voltage.
