1. A system comprising:

  • a processor circuit;

    a power converter circuit coupled to the processor circuit and configured to provide, to the processor circuit, regulated DC power supply signals including first and second voltage signals;

    wherein the processor circuit comprises a semiconductor die, the semiconductor die including first and second power domains configured to receive the first and second voltage signals, respectively, and wherein the processor circuit further comprises a first integrated inductor circuit and a first integrated capacitor circuit;

    wherein each of the first and second power domains includes at least one power rail, and wherein each of the power rails is configured to provide different power signals to respective consumer circuits, andwherein a first power rail in the first power domain is coupled to a second power rail using the first integrated inductor circuit and the first integrated capacitor circuit.
