Abstract
Transmission line impedance matching for matching an impedance discontinuity on a transmission signal trace with one or more non-transmission traces disposed near the transmission signal trace at a region corresponding to the impedance discontinuity.
Claims15
A method, comprising:
- providing a transmission signal trace, the transmission signal trace having an impedance discontinuity, a first length, and a first width;
- determining a second length of a non-transmission trace, wherein the second length of the non-transmission trace is substantially less than the first length of the transmission signal trace;
- and
- determining a location to dispose the non-transmission trace near the transmission signal trace to electromagnetically couple the non-transmission trace to the transmission signal trace at a region corresponding to the impedance discontinuity in the presence of a current on the transmission signal trace.

An apparatus, comprising:
- a transmission signal trace having an impedance discontinuity, a first length, and a first width;
- a first non-transmission trace disposed near the transmission signal trace at a region corresponding to the impedance discontinuity, the first non-transmission trace having a second length that is substantially less than the first length of the transmission signal trace, the first non-transmission trace 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 non-transmission trace, the second non-transmission trace disposed near the transmission signal trace at a region corresponding to the impedance discontinuity, the second non-transmission trace having a third length that is substantially less than the first length of the transmission signal trace, the second non-transmission trace 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.
