Abstract
A system and method is provided that improves the propagation characteristics of an electrical conducting signal wire on an integrated circuit. The system includes a pair of parallel shielding wires positioned on opposite longitudinal sides of the signal wire. A shielding signal is applied to the shielding wires. The shielding signal is out of phase with the signal of interest propagated on the signal wire.
Claims15
A system for propagating an electrical voltage signal, comprising:
- an elongated electrical conducting signal wire over which the electrical voltage signal is propagated;
- a pair of electrical conducting shielding wires positioned parallel to and on opposite longitudinal sides of said signal wire;
- and
- a shielding signal applied to said pair of shielding wires, said shielding signal being out of phase with the electrical voltage signal.
A method of improving signal propagation characteristics on an electrical conducting signal wire, comprising the steps:
- providing a pair of parallel electrical conducting shielding wires on opposite longitudinal sides of the signal wire;
- applying a shielding signal to said pair of shielding wires, said shielding signal being out of phase with a signal of interest propagated on said signal wire.
An integrated circuit, comprising:
- a signal wire connected between a first electrical component and a second electrical component of the integrated circuit, said signal wire being configured to facilitate the propagation of an electrical signal of interest from said first electrical component to said second electrical component;
- a pair of parallel shielding wires positioned on opposite longitudinal sides of said signal wire;
- and
- a shielding signal propagated on said shielding wires, said shielding signal being out of phase with said signal of interest.
