Abstract

A shared charge pump partly disposed on an integrated circuit provides a first output voltage and a second output voltage to a coupled device, and includes: a plurality of switches coupled to a first input voltage and a second voltage, wherein the switches are individually opened and closed according to control logic; and a capacitor disposed outside the IC for storing charge according to the first input voltage and the second input voltage during a first phase, discharging to generate the first output voltage during a second phase, and discharging to generate the second output voltage during a third phase. The shared charge pump enters the first phase, the second phase and the third phase via control of the plurality of switches, and a sequence of the phases can be dynamically switched according to a level of the first output voltage and the second output voltage determined at the capacitor.
