基于螺旋谐振环结构的UWB同步开关噪声抑制电源平面
Ultra-wideband Suppression of Simultaneous Switching Noise Using Spiral Resonator Structure Mounted Power Plane
摘要
Abstract
To solve the limitations of existing methods of simultaneous switching noise( SSN) suppression, an ultra-wideband ( UWB ) suppression of SSN using spiral resonator structure mounted power plane is presented. By studying its equivalent circuit model,full-wave finite element method( FEM) is applied to analyze the power integrity both in frequency domain and time domain. The simulated results display that the SSN suppression bandwidth is broadened from 0 . 13 GHz to 20 GHz under a noise suppression margin of -40 dB, the SSN suppression characteristics are greatly improved in lower frequencies, approximately 16 . 97 GHz and 17 . 73 GHz of stopband bandwidth improvement over the conventional UC-EBG and pla-nar-EBG power plane,respectively. When noise frequency is 20 GHz,the amplitude is 1 V injected,the noise voltage is suppressed to 0. 25 mV.关键词
