Crosstalk reduction using open-loop resonators for printed circuit boards traces

Abstract

In this paper, a new method is proposed to alleviate induced crosstalk noise in traces of printed circuit boards (PCBs). We show that open-loop resonators (OLRs) are capable to mitigate the induced noise. Electromagnetic coupling between two adjacent wires is considered to study the crosstalk noise, as well. Several methods such as the 3W rule spacing and the guard trace with distributed vias are applied to reduce the crosstalk noise. Simulation results show that OLR insertion between aggressor and victim wires reduce the crosstalk without degrading the wire response. The wire structures in the study are examined using ADS momentum tools.
