ABSTRACT:
A charge pump system using a current based regulation method, in addition to the typical voltage based regulation methods is presented. The current flow in the charge pump is determined independently of the output voltage. By sensing the current going through the charge pump while its output is being regulated to the target level, the strength of charge pump can be dynamically adjusted in term of regulation level, branch assignment, clock frequency, clock amplitude, and so on. Indirectly sensing the current going through pump (not in serial with output stage to allow additional IR drop) will allow the pumps to have matrix of V and I to better adjust the charge pump parameters for current saving and ripple reduction.
