摘要
介绍在PCB板上添加去藕电容进行EMC和信号质量的优化设计方法。详细说明在添加去耦电容时,去耦电容取值大小的计算、电容类型的选择、去耦电容的摆放、不同线路的频率和上升速度大小、线路板各层之间以及时钟的自协调频率的配合、防止共振的产生等这些应用去耦电容时关注和考虑的内容。
The design of PCB is much more difficult with the appearance of much high frequency signal, the Electro Magnetic Compatibility design becomes a prominent problem at the time. The article gives the corking method to improve the quality of the signal. The main view includes： calculating the numerical value of the capacitance, choosing the type of the capacitance and putting the capacitance in circuit and so on.
