摘要:
PCB设计仿真是提高电子设备电磁兼容性能十分有成效的方法,为减小电源/地平面间高频谐振阻抗对电路带来的危害,本文采用电路板级仿真软件SIwave对某GPS电路板进行谐振仿真. 从频域角度分析板间谐振及对应频点的电压分布,比较优化前和优化后的仿真结果,从而改善PCB的电磁兼容性.
Abstract:
PCB design and simulation is an effective way to improve the electromagnetic compatibility of electronic equipment. Based on the SIwave software,one GPS PCB structure mode for resonance is established for reducing the harm caused by the high frequency resonance impedance of the power supply to the ground plane. In frequency domain,the resonant frequency and the voltage between multilayer PCB are analyzed in this paper. To promote EMC,simulation of initial result and improving one are compared.
