Patent ID: 7432779

Claim:
An apparatus, comprising: a transmission signal trace having an impedance discontinuity, a first length, and a first width; a first set of a plurality of non-transmission traces disposed on a single side of the transmission signal trace and near the transmission signal trace at a region corresponding to the impedance discontinuity, the plurality of non-transmission traces in the first set each having a length that is substantially less than the first length of the transmission signal trace, the plurality of non-transmission traces in the first set each electromagnetically coupled to the transmission signal trace in the presence of a current on the transmission signal trace to provide a matched impedance on the transmission signal trace; and a second set of one or more non-transmission traces disposed on a single side of the transmission signal trace opposite the first set, wherein the number of non-transmission traces in the second set does not exceed the number of non-transmission traces in the first set.
