Abstract
An integrated circuit includes a first circuit and a first power supply line for powering the first circuit. A first intra-chip clock interface generates a first clock signal on the first power supply line. A second power supply line is coupled to the first power supply line and further powers the second circuit. A second intra-chip clock interface recovers the first clock signal from the second power supply line. The second circuit operates based on the first clock signal.
Claims17
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.
