Claim Text:
1. An apparatus comprising: an input port; an output port; one or more voltage regulator circuit components configured to provide for a change from an input voltage at the input port to an output voltage at the output port; and one or more graphene capacitors configured to have a quantum capacitance that is dependent on the output voltage, wherein the one or more graphene capacitors provide smoothing to the output voltage, wherein the smoothing is provided at least by a kinetic energy of one or more charge carriers in the one or more graphene capacitors, wherein the one or more graphene capacitors have a substrate dopant configured to change a Fermi level relative to an un-doped substrate, and wherein the substrate dopant and an amount of the substrate dopant are selected at design time to map a predetermined relationship between the quantum capacitance and a voltage across the one or more graphene capacitors.
