Pumping controller for a plurality of charge pump units

Abstract

In one example, a system comprises a plurality of charge pump units connected in parallel to receive an input voltage and to generate an output voltage greater than the input voltage; and a pumping controller to provide a pumping signal to a first charge pump unit of the plurality of charge pump units and to provide sequentially delayed versions of the pumping signal to the other charge pump units of the plurality of charge pump units, the pumping controller comprising a plurality of circuit blocks, each of the plurality of circuit blocks comprising a delay circuit and a latch.
