Claim Text:
1. A load-sensing voltage charge pump system with reduced output voltage ripple, comprising: a plurality of reference voltage inputs comprising a target voltage and a sum of said target voltage and a plurality of voltage offsets, each of said plurality of voltage offsets being offset from said target voltage input by a different amount; a plurality of voltage charge pump segments equal in number to said plurality of reference voltage inputs, each of said plurality of voltage charge pump segments including: a boosted line connected in parallel to said sensed output voltage of each of said plurality of voltage charge pump segments, said boosted line being connected to said output load, said boosted line receiving each said current of each one of a plurality of different frequencies corresponding to each of a plurality of oscillators in each one of said plurality of voltage charge pump segments that is enabled by its corresponding regulator to produce said target voltage with reduced output voltage ripple.
