| Abstract: | In high speed printed circuit board design,the interference in the design of hybrid circuit is a tough problem.Especially the analog signals are the sources of other signals,whether or not receive and transform signals accurately is the key factor of PCB design.The mechanism of interference source is analyzed in detail.With the experience of my PCB design,the general design rules of hybrid circuit and the approved corresponding solutions are given.These measures effectively reduce the mutually disturb with a PCB design as example. |
