基于传递函数的高速互连线串扰分析

Crosstalk Analysis for High-speed Interconnect Lines Based on Transfer Function

针对互连线系统在高速信号激励下产生的串扰问题,导出高速互连线的时域分布参数系统模型,建立从激励电压到攻击线末端和受害线两端电压相应的传递函数,从系统的角度研究串扰噪声问题。仿真结果表明了该方法的有效性,与数值方法相比更具有一般性。

Crosstalk often happens under the excitement of high-speed signals in interconnect systems. This paper deduces a system model of high-speed interconnect lines with distributed parameters in time domain, sets the transfer function from the exciting voltage to the voltage of the end of the aggressive line and both ends of the victim line correspondingly, and studies the problem of crosstalk noises from the systematic aspect. Simulation results demonstrate the validity and the universality of the method compared with the numerical method.
