Abstract

An apparatus and method for generating a plurality of output signals that can be used for driving a corresponding plurality of charge pumps from a signal oscillating between a first and second logic state. The apparatus includes a plurality of shift register stages coupled in series, where the shift register stages shift a latched logic state in response to the oscillating signal. Further included in the apparatus is a duty cycle correcting circuit coupled to the output terminals of the shift register stages which generates each of the output signals that can be used to drive a charge pump based on the latched logic state of two of the shift register stages.
