Abstract
Embodiments of the present invention include charge pump circuits and methods. In one embodiment, a first charge pump receives a voltage and generates a first charge pump output voltage and current for supplying the power requirements of a circuit. A second charge pump is coupled in series with the first charge pump. The second charge pump generates a second charge pump output voltage and current for supplying different power requirements of the circuit. In one embodiment, the first charge pump provides a high current low voltage output to a first circuit and the second charge pump provides a low current high voltage output to a second circuit. Capacitors of the first charge pump may be external to an integrated circuit and capacitors of the second charge pump may be internal to the integrated circuit.
