| 摘 要： | 随着现代高速数字电路的快速发展,同步开关噪声(SSN)问题变得越来越突出。该文提出了一种适用于高速数字电路中抑制同步开关噪声的新型宽带平面电磁带隙(EBG)结构,并用Ansoft HFSS软件对该电磁带隙结构进行数据仿真分析。仿真结果表明,在抑制深度为-30dB时,其阻带范围为0.2~5.6 GHz,与传统的L-bridge型电磁带隙结构比较,阻带下限截止频率下降了500 MHz,阻带带宽增加了1.4GHz,相对带宽增加了38.1%,且能全向抑制同步开关噪声。

| Abstract: | With the rapid development of modern high speed digital circuits, simultaneous switching noise(SSN) problem becomes more and more prominent. A novel wide band planar electromagnetic band gap(EBG) is proposed for the suppression of SSN in high speed digital circuits. The proposed electromagnetic band gap is simulated and analyzed by using Ansoft HFSS. The simulation results show that the -30 dB suppression bandwidth ranges from 0.2 GHz to 5.6 GHz. Compared to the L bridge EBG, the lower cut off frequency is decreased by 500 MHz, the bandwidth is increased by 1.4 GHz, the relative bandwidth is increased by 38.1%. At the same time, it can suppress the simultaneous switching noise omnidirectionally. |
