  • 微帶傳輸線間串擾導致欲傳送信號變異、失真,引發信號整性的問題;串擾有分為近端與遠端,遠端串擾因為累加的關係,對信號失真影響最大;本文使用交錯式殘段改善串擾,搭配連續直交表與田口法,輔以功率頻譜和的目標函數來達成最佳配置。


    Cosstalk causes variation and distortion to the signal transmitted in the
    microstrip line. It raises the concern of signla integrity. Cross talk can be classified as near end crosstalk and far end crosstalk, the accumulation property of far end crosstalk causes the large impa ct to signal integrity. The thesis propose alternated stub to improve the far end crosstalk, combine the consecutive orthogonal array and taguchi method with the object function – Sum of power from S-Parameter to achieve the optimized configuration.
