Analysis of crosstalk of complicated striplines in a FR-4 multilayer PCB
다층기판에서 복잡한 스트립라인 구조의 누화 해석
Abstract
In this paper, we find the values of near-end crosstalk coefficient in striplines of a FR-4 multilayer PCB by an analytic method and a HSPICE simulation method, and define calcualtion errors in an analytic method and define the application range, and simualte near-end crosstalk coefficients of the FCT (fast CMOS TTL) in complicated striplines by HSPICE and analyze near-en crosstalk coefficients in relation to dielectric thickness and trace spaces of striplines. As a result, we analyze coupling structure of the near-end crosstalk in the coplicated sstriplines that are impedance matched and define a coupling formula of near-end crosstalk coefficients in general complicated striplines. Especially, it is approximated in the layout grade rule.
