摘　　要：分析了高速电路设计中由于终端阻抗不匹配而引起的信号反射现象 ,论述了几种可以有效的消除或削弱信号反射的终端匹配技术 ,包括简单的并联终端匹配 ,戴维南并联终端匹配 ,RC并联终端匹配和串联终端匹配技术 .The paper analyzed the phenomenon that mismatched impedance will cause signals to reflect back and forth down the transmission line in the high speed board design.Several termination techniques which can effectively eliminate, or at least reduce the reflections are introduced. Termination techniques include the simple parallel termination,Thevenin parallel termination, RC parallel termination and serial termination,whose structures,applications,advantages and disadvantages are expatiated sufficiently.It's essential for high speed system to an appropriate termination.
