Abstract
The present invention discloses a voltage up converter, including: a detector for detecting a level of an internal power to generate the internal power higher than an external power; an asymmetrical oscillator for generating a frequency in which a high level width and a low level width are different according to the output from the detector; and a pump for generating the internal power by performing a pumping operation according to the output from the asymmetrical oscillator.
