摘要
从数字电路中时钟电路的辐射模型出发,分析了影响其辐射电磁干扰(EMI)的关键因素,进而探讨了降低其干扰的方法,并对这些措施的效果进行了比较,从而得到综合效益比较好的方法。最后通过实验,比较了这些方法的实际效果,验证了理论分析和数字仿真结果的正确性。
Based on the radiation model of the clock circuits on the digital PCB,the key issues which can affect the radiation interference on the digital PCB are studied.The methods to suppress the radiation interference are presented and the effects are compared with each other, therefore, the most effective method is derived from the results mentioned above. The theory analysis and simulation results are verified by the experimental results.
