Abstract
A load-sensing voltage charge pump system may include a plurality of reference voltage inputs including a target voltage input. The system may also include a plurality of voltage charge pump segments equal in number to the plurality of reference voltage inputs. A voltage charge pump segment may include: a regulator that receives a reference voltage, and a voltage charge pump that outputs a current to a load at a sensed voltage. The regulator may enable each of the voltage charge pump segments, when the sensed voltage is less than or equal to the one of the reference voltages and the target voltage. The system may include a boosted line connected in parallel to an output of each of the voltage charge pump segments. The boosted line may receive the current at the sensed voltage from each of the voltage charge pump segments that is enabled.
