ABSTRACT:
Transmission line impedance matching is described for matching an impedance discontinuity on a transmission signal trace. The apparatus includes a transmission signal trace and a non-transmission trace. The transmission signal trace has an impedance discontinuity, a first length, and a predetermined first width. The non-transmission trace is disposed near the transmission signal trace at a region corresponding to the impedance discontinuity. The non-transmission trace has a second length that is substantially less than the first length of the transmission signal trace. Additionally, the non-transmission trace is configured to be 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.
