Measuring and controlling current consumption and output current of charge pumps

Measuring and controlling current consumption and output current of a charge pump by measuring a first current coming into the charge pump; and measuring a second current coming into a driver for at least one of the one or more stages of the charge pump. A control loop may one or more parameters of the charge pump and/or a load connected to the charge pump, such as by adjusting one or more of: a supply voltage; a stage's voltage; the stage's frequency and/or duty-cycle; and the number of stages, or by decreasing the current consumption by adjusting a load connected to the output of the charge pump pipe. The first and second currents may be compared with first and second reference currents. A load connected to the charge pump may comprise non-volatile memory cells, and the charge pump may be implemented on a same integrated circuit chip as the memory cells.
