Abstract:
1. An apparatus for decreasing the propagation delay time of an electrical signal transmitted from a source along a conductor in a circuit, the apparatus comprising: a first conductor having a length extending from a first area of the circuit to a second area of the circuit and for carrying an electrical signal, the first conductor having a first end electrically coupled to the source capable of providing the electrical signal and a second end electrically coupled to a destination; a second conductor having a length extending from the first area of the circuit to the second area of the circuit and located proximate the first conductor and extending substantially parallel to and along the first conductor, the second conductor having a first end electrically coupled in the first area of the circuit to the source and having a second end unconnected in the second area of the circuit; and a third conductor having a length extending from the first area of the circuit to the second area of the circuit and located proximate the first conductor and extending substantially parallel to and along the first conductor, the third conductor having a first end electrically coupled in the first area to the source and having a second end unconnected in the second area of the circuit, and wherein the second and third conductors reduce the effective capacitance of the first conductor thereby increasing the speed of the electrical signal when transmitted along the first conductor, wherein the second conductor is disposed below the first conductor and the third conductor is disposed above the first conductor.
