【摘要】 针对MCM互连,分析了反射噪声产生的原因及其对电路性能的影响。基于终端匹配理论研究了简单并联端接、戴维南端接和RC端接等几种终端匹配方法。选取MCM的典型互连参数和互连线的等效模型,使用PSPICE对三种不同的终端匹配方法进行仿真,分析了三种终端匹配方法各自的特点。在时钟频率较高的MCM中,可采用终端匹配技术来有效的抑制互连线上的反射噪声。更多还原

【Abstract】 Aimed at MCM-interconnection the paper analyzed the cause of reflection and indicated the influence of reflection on circuit performance.Based on terminal-matching theory,it researched into some terminal-matching methods such as simple parallel termination,Thevenin termination and RC termination.Choosing typical interconnection parameters and equivalent model of MCM,compared the characteristic of each method by analysis of PSPICE simulation.In the higher clock frequency MCM,terminal-matching method can be used to control interconnection reflection.更多还原
