摘　　要：针对旁路电容器的滤波特性及理想电容器和实际电容器之间的差别,提出选择旁路电容器的一些建议。在此基础上,探讨电源扰动及地弹噪声的产生机理,给出旁路电容器放置的解决方案。The characteristics of bypass capacitors and the difference between ideal capacitors and practical ones are analyzed. Some suggestions are proposed on the selection of bypass capacitors. Besides, some research has been done on the cause of the power-bounce and ground-bounce perturbations. Furthermore, the best bypass capacitors layout is given.
