    • 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.
    • 描述传输线阻抗匹配以匹配传输信号迹线上的阻抗不连续性。 该装置包括发送信号跟踪和非传输迹线。 发送信号迹线具有阻抗不连续性,第一长度和预定的第一宽度。 在与阻抗不连续性对应的区域处,将非传输迹线布置在发射信号迹线附近。 非透射迹线具有基本上小于发射信号迹线的第一长度的第二长度。 此外,非传输轨迹被配置为在存在传输信号迹线上的电流的情况下电磁耦合到传输信号迹线,以在传输信号迹线上提供匹配的阻抗。
