<p>This disclosure presents a method of canceling inductance-dominated crosstalk using a capacitive coupling circuit; it also presents a method of calibrating, selecting and programming a capacitance value used for coupling, so as to add a derivative of each aggressor signal to each victim signal, and thereby negate crosstalk that would otherwise be seen by a given receiver. In the context of a multiple-line bus, cross-coupling circuits may be used between each pair of“nearest neighbors,”with values calibrated and used for each particular transmitter-receiver pair. Embodiments are also presented which address crosstalk induced between lines that are not nearest neighbors, such as, for example, for use in a differential signaling system.</p> |
