1. An integrated circuit comprising:

  • a first power supply line for powering a first circuit; and

    a first intra-chip clock interface coupled to the first power supply line that generates a first clock signal on the first power supply line;

    a second circuit that operates based on the first clock signal;

    a second power supply line for powering the second circuit;

    a high-pass filter for coupling the first power supply line to the second power supply line, wherein the high-pass filter passes the first clock signal; and

    a second intra-chip clock interface coupled to the second power supply line that recovers the first clock signal from the second power supply line.
