发布时间:2018-07-31 08:25
【摘要】:针对印刷电路板中电源平面与接地平面间的同步开关噪声抑制问题,提出了一种新型的超宽带二维电磁带隙电源平面.新型电磁带隙电源平面的阻带带隙抑制深度为-30dB,阻带宽度为11.14GHz,下限截止频率为0.28GHz,其同步开关噪声抑制特性的测量结果与仿真结果吻合良好.与同参数的Lbridged电磁带隙结构比较,新型电磁带隙结构的阻带带宽增加约48.7%,下限截止频率降低0.46GHz.当采用差分线对传输信号时,新型电磁带隙电源平面对信号的完整性影响较小,有助于改善高速数字电路系统的电磁兼容性.
[Abstract]:A novel ultra-wideband two-dimensional electromagnetic bandgap power supply plane is proposed to suppress the synchronous switching noise between the power supply plane and the grounding plane in printed circuit boards (PCB). The suppression depth of stopband gap is -30 dB, the stopband width is 11.14 GHz, and the lower cut-off frequency is 0.28 GHz. The measured results of the noise suppression characteristics of the synchronous switch are in good agreement with the simulation results. Compared with the Lbridged electromagnetic band gap structure with the same parameters, the stopband bandwidth of the new electromagnetic band gap structure is increased by about 48.7 and the lower cut-off frequency is reduced by 0.46 GHz. When the differential wire is used to transmit the signal, the new electromagnetic bandgap power plane has little influence on the signal integrity, which is helpful to improve the electromagnetic compatibility of the high-speed digital circuit system.
