Abstract: A system for providing a load current at a specific voltage to a circuit block of an integrated circuit (IC) includes a plurality of charge pumps and a control circuit to generate a control signal for each of the charge pumps. The control signal causes each of the charge pumps to be enabled, partially enabled, or disabled, and controls at least one of the charge pumps independently of the other charge pumps.

Abstract: A system for providing a load current at a specific output voltage to a circuit block of an integrated circuit (IC) includes a supply node at a supply voltage, a charge pump, and a cross-coupling circuit. The charge pump includes a first a first capacitor to charge while a first clock signal is high and a second capacitor to charge while a second clock signal is high. Each of the capacitors has a top plate node, a bottom plate node, a ground node, and an intermediate node between the bottom plate node and the ground node. The cross-coupling circuit couples the intermediate node of the first capacitor to the supply node while the second clock signal is high and couples the intermediate node of the second capacitor to the supply node while the first clock signal is high.
