Connector based compensation of via stub effects

摘要

Aspects of the disclosure provide a connector. The connector includes a first signal conductor. The first signal conductor is configured to receive a first electronic signal that includes multiple frequency components. The first signal conductor includes a plurality of conductor portions having portion-dependent impedances. The first signal conductor is configured to transfer the first electronic signal between a via on a circuit board that has a via stub and an electronic device to reduce via stub effects. In addition, in an example, the connector includes a second signal conductor to transfer a second electronic signal. The second electronic signal and the first electronic signal are a pair of differential signals. In an example, the first signal conductor and the second signal conductor have different via stub effects. The first signal conductor and the second signal conductor are configured with regard to each other to have portion-dependent differential impedances to mitigate the different via stub effects.

1. A connector comprising:
a first signal conductor that is configured to receive a first electronic signal that includes multiple frequency components, the first signal conductor including a plurality of conductor portions characterized by portion-dependent impedances, the first signal conductor being configured to transfer the first electronic signal between a via on a first circuit board that has a via stub and a second circuit board that has a via stub to reduce via stub effects, wherein the first signal conductor further comprises: a first longitudinal portion that has a first impedance; a second longitudinal portion that has a second impedance that is different than the first impedance; and a third longitudinal portion that has a third impedance that is different than the second impedance.
