<p>PURPOSE: A charge pump circuit and a method for charge pumping are provided to generate a booted voltage having a stable level regardless of the change of a boost voltage ratio by allowing a capacitor to have a period in which a charged voltage level is changed in advance. CONSTITUTION: In a charge pump circuit and a method for charge pumping, a plurality of capacitors(C11,C12,C13) perform a voltage boosting operation. A switch control part(310) responses to a boosting ratio and generates a plurality of switch control signals. A switch element(320) controls a plurality of capacitors.</p> |
