摘要

采用拼接去耦电容抑制电源/地平面对的边缘电磁辐射。将连接电源和地的解耦电容的寄生效应(ESL和ESR)引入到法模波导理论中,以优化解耦电容的布置和规格。在实际结构中的应用表明,通过选择合适的ESL,可以在几GHz范围内额外抑制18dB的EMI,通过选择合适的电容值,可以在几百MHz范围内抑制超高的EMI。全波仿真和实验验证了设计思想。

Optimal decoupling capacitors design for suppressing edge radiation of power/ground planes
Stitching decoupling capacitors are utilized to suppress the edge electromagnetic radiation in a pair of power/ground planes in this paper. The parasitic effects, ESL and ESR, of decoupling capacitors connecting the power and ground in the board periphery are introduced into the normal mode waveguide theory to optimize the placements and specification of the decoupling capacitors. Applications to practical structures demonstrate an additional 18dB EMI suppression up to several GHz range by choosing suitable ESL and an ultra-high suppression at several hundred MHz by choosing suitable capacitor value. Both the full-wave simulation and experiment validate the design idea.
