Abstract

Abstract:

Crosstalk is one of the bottlenecks in high-speed circuits for rate and density continuing increasing. Aiming at the problem of crosstalk between multiple transmission lines, a crosstalk cancellation method of three coupled microstrip lines based on eigen value decomposition of coupled transmission lines-channel transmission matrix was proposed. The circuit implementation structure of the method was studied and the circuit parameters were provided. Simulations show that crosstalk can be mostly eliminated and the quality of eye diagram can be improved obviously.

Key words: crosstalk, multiple transmission lines, channel transmission matrix, microstrip line
