Abstract
The present disclosure describes a charge pump circuit, comprising a first switch, a second switch and a flying capacitor. The first switch receives driving voltage when the clock signal is at the first level, while the second switch receives driving voltage at the second level. The flying capacitor charges via the first switch and discharges via the second switch to generate the output voltage. When the power supply voltage is lower than the preset output voltage, the driving voltage for the first switch is lower than that for the second switch. The present disclosure adaptively regulates the current-carrying capabilities of the first and second switches in accordance with the magnitude of the power supply voltage to ensure that the voltage difference across the flying capacitor is less affected by changes in the power supply voltage, thereby enhancing circuit stability.
