【摘要】：在高速数字系统中,信号完整性问题越来越突出,信号速率和设计密度的不断提高使得串扰上升为主要因素之一。先研究了基于矩形谐振腔的串扰抑制方法;然后与三倍线宽方法(3W方法)和有过孔接地的防护线方法的对比分析表明,矩形谐振腔方法对微带线间近端串扰的抑制能力不理想,但对远端串扰的抑制非常有效,在频域仿真中远端串扰幅度可提高12dB和8dB,在时域仿真中远端串扰峰值分别为前两种方法的18.2%和23.1%;最后进一步研究了矩形谐振腔的结构参数(间距、长度和宽度)对远端串扰的影响,发现这三个参数存在一组最优值,能最大程度地减小远端串扰。
[Abstract]:In high-speed digital systems, the problem of signal integrity is becoming more and more serious, and the increasing of signal rate and design density make crosstalk rise as one of the main factors. Firstly, the crosstalk suppression method based on rectangular resonator is studied. The comparison of the method with tripling linewidth method (3W method) and the protection line method with over-hole grounding shows that the rectangular resonator method is not effective in suppressing the near-end crosstalk between microstrip lines. But the suppression of remote crosstalk is very effective. In frequency domain simulation, the amplitude of remote crosstalk can be increased by 12dB and 8dB. In time domain simulation, the peak value of remote crosstalk is 18.2% and 23.1of the former two methods, respectively. Finally, the influence of the structural parameters (spacing, length and width) of the rectangular resonator on the far end crosstalk is studied. It is found that the three parameters have a set of optimal values, which can minimize the far end crosstalk.
