抑制同步开关噪声的新型电磁带隙电源平面
Novel power plane with an electromagnetic bandgap structure for suppression of simultaneous switching noise
摘要
Abstract
For ultra‐wideband suppression of simultaneous switching noise between the power plane and the ground plane within the printed circuit board , a novel power plane with planar electromagnetic bandgap structures is proposed . When the suppression depth of the bandgap is -30 dB , the width of the stop‐band is 11.14 GHz and the lower cut‐off frequency is 0.28 GHz . The simulated and measured results of the novel power plane with planar electromagnetic bandgap structures are in good ageement . The new EBG's stop‐band is dramatically increased about 48.7% , with the lower cut‐off frequency decreased to 0.46 GHz compared with the L‐bridged EBG structure with the same parameters . The signal integrity of the new EBG power plane can be improved by using differential transmission lines . This work is helpful for the EMC improvement of high speed digital circuits .关键词
