Abstract:
1. An apparatus comprising a switched capacitor charge pump configured to provide a voltage conversion between terminals including a high voltage terminal and a low voltage terminal, a compensation circuit coupled to a first terminal of the charge pump for driving a load by the charge pump, the compensation circuit providing a capacitance configurably coupleable to the first terminal of the charge pump, and a controller coupled to the charge pump and the compensation circuit, the controller comprising an output for configuring the compensation circuit, and one or more sensor inputs for accepting one or more sensor signals characterizing operation of at least one circuit selected from the group consisting of the charge pump and peripheral circuits coupled to the charge pump, wherein the controller is configured to configure the compensation circuit according to the one or more sensor signals to affect efficiency of power conversion between a power source coupled to the charge pump and the load coupled to the charge pump via the compensation circuit, wherein the one or more sensor signals include a sensor signal that characterizes time variation of a current passing to or from the charge pump via the compensation circuit.
