摘要： A charge pumping circuit is provided to regulate the amount of charge to be pumped according to a driving voltage to reduce the loss of power and increase charge pumping efficiency. The charge pumping circuit includes: a driving voltage sensing unit sensing a driving voltage to generate one or more sensing signals for determining the amount of charge to be pumped; a multi-level clock generation unit generating a pair of clock signals each having an amplitude corresponding to a signal value of each of the one or more sensing signals; and a charge pumping unit charging the pair of clock signals to generate a charged voltage, adding the charged voltage to the driving voltage, and outputting the same.
