Abstract: An integrated circuit-based charge pump generates an output voltage having a greater magnitude than a power supply voltage. The charge pump has a charge pump section having a plurality of alternating stages driven by first and second alternating, non-overlapping clock signals, said plurality of alternating stages including an input stage for receiving the power supply voltage and an output stage for generating at a last stage node a last stage voltage having a greater magnitude than the power supply voltage. A gating transistor is coupled at a drain terminal to the last stage node, wherein the gating transistor is clocked by one of said clock signals and is biased so that the gating transistor, during a boost phase, gates the last stage voltage to a load coupled to the source terminal of the gating transistor without a voltage drop and, at other times, turns off to prevent charge from flowing from the load into the last stage node of the charge pump section.

Abstract: The voltage regulator includes a regulator circuit, connected between a high potential and a low potential, regulating an output voltage based on an input voltage. The regulator circuit includes a changing circuit which changes at least one of a voltage range of the output voltage and a rate at which the output voltage changes with respect to changes in the input voltage. The changing circuit selectively increases a maximum value of the voltage range of the output voltage, and also selectively increases the rate at which the output voltage changes with respect to changes in the input voltage.
