Abstract
Disclosed is a charge-pump and a dynamic charge-pump device including the same. By switching the plurality of voltage sources, the output voltage of the charge-pump can be compensated, and changed output voltage of the charge pump is utilized to adjust a voltage as power source or ground source of a loading circuit. A detection circuit may further be included in the charge-pump for detecting the voltage or current of the loading circuit, and the minimum output voltage of the charge pump may be chosen to adjust the voltage-drop of the loading circuit, and the variation of the voltage of the loading circuit can be brought back within a predetermined range, such that the operational efficiency of the loading circuit may not be influenced. Moreover, the adjustment may be performed according to the different operation modes of the loading circuit, and the power consumption can be decreased.
