ABSTRACT:
A charge pump circuit for generating an output voltage is described. The charge pump includes multiple output generation stages connected in series and a corresponding set of multiple gate stages connected in series, where the output stages have the same structure as the corresponding gate stages. The switches that the provide the output of each output generation stage are controlled by the corresponding gate stage. The number of output stages that are active in boosting the voltage self-adapts according to the output level being regulated, with the later stages changing from a boosting operation to a filtering function with not being used to active boost the output.
