Abstract

Aiming at the crosstalk problem between multiple coupled transmission lines in high-speed interconnection, a crosstalk cancellation method based on the inverse matrix of the Coupled Transmission Lines-Transfer Function Matrix (CTL-TFM) is proposed. The method first constructs the transfer function matrix of multiple coupled microstrip lines, and then designs the corresponding circuit for the inverse matrix of the transfer function matrix at the output ports. This ensures that the transfer function matrix of the entire system is reduced to a unit matrix, effectively reducing the crosstalk between transmission lines. Simulation results show that the quality of the signal eye diagrams at the outputs of all three coupled microstrip lines is significantly improved after using this method, and the crosstalk amplitude and jitter are substantially reduced.
