Abstract
An electronic device includes a reconfigurable charge pump including pump units that can be arranged differently for varying an output voltage generated by the reconfigurable charge pump; a pump regulator coupled to the reconfigurable charge pump, the pump regulator configured to monitor the output voltage and turn the reconfigurable charge pump on or off based on the output voltage; and an arrangement control mechanism coupled to the pump regulator, the arrangement control mechanism configured to control operation of the pump regulator based on the output voltage to generate arrangement control output, wherein the arrangement control output controls electrical connections between the pump units.
Claims14
An electronic device, comprising:
- a reconfigurable charge pump including pump units that can be arranged differently for varying levels of an output voltage generated by the reconfigurable charge pump;
- a pump regulator coupled to the reconfigurable charge pump, the pump regulator configured to monitor the output voltage and turn the reconfigurable charge pump on or off based on the output voltage;
- an arrangement control mechanism coupled to the pump regulator, the arrangement control mechanism configured to:
- repurpose the pump regulator based on the output voltage, and
- generate the mode output based on comparing the output voltage or a derivation thereof to a set of threshold level;
- and
- wherein:
- the pump regulator is repurposed to control electrical connections between the pump units according to the arrangement control mechanism.
