Abstract:
1. A system for providing a load current at a specific voltage to a circuit block of an integrated circuit (IC), comprising: a plurality of charge pumps; and a control circuit to generate a control signal for each of the charge pumps; wherein the control signal causes each of the charge pumps to be enabled, partially enabled, or disabled; and wherein the control signal controls at least one of the charge pumps independently of the other charge pumps, wherein each charge pump comprises 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, wherein each of the capacitors comprises 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 system further comprising: a cross-coupling circuit to:
