| Abstract: | 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. |
