Regulation circuit for a charge pump and method of regulation

摘要

The present invention relates to a regulation circuit for a charge pump (12) and to a method of regulating a charge pump. The regulation circuit (10) comprises
- a detector (22) operable to analyze a temporal activity of the charge pump, and
- a pump clock generator (24) coupled to an output (25) of the detector and having an output (26) coupled to a clock input (13) of the charge pump to vary a pump clock frequency (50) of the charge pump in dependence of the analysis of the detector, or
- a supply or voltage generator coupled to an output of the detector and having an output coupled to the charge pump to vary an amplitude of a clock signal within the charge pump in dependence of the analysis of the detector.
