Abstract
The present invention is for preventing a charge pump from an unnecessary output voltage loss generated by a threshold voltage of a metal-oxide silicon (MOS) transistor. An apparatus for amplifying an inputted voltage includes an amplifying block including at least two pumping units for amplifying the inputted voltage to generate an output voltage; and at least two pumping capacitors, each coupled between two pumping units for supplying a charge in order to amplifying the output voltage of each pumping unit, wherein the pumping unit has a transferring block for transmitting the inputted voltage; and an activation block for activating the transferring block.
