摘要

本文研究了双电源双芯配电网中同时开关噪声问题。这是通过减小PDN的导纳矩阵，然后使用矢量拟合的有理函数近似计算频域阻抗来实现的。本文提出了一种利用开关电流计算同时开关噪声的方法，描述了开关电流的特性和细节。因此，使用MATLAB和PSpice工具对结果进行了讨论和执行。结果表明，由于电磁耦合，同一PCB中存在多个芯会影响SSN。

Investigation and Analysis of the Simultaneous Switching Noise in Power Distribution Network with Multi-Power Supplies of High Speed CMOS Circuits

The paper studies a simultaneous switching noise (SSN) in a power distribution network (PDN) with dual supply voltages and two cores. This is achieved by reducing the admittance matrix of the PDN then calculating frequency domain impedance with rational function approximation using vector fitting. This paper presents a method of computing the simultaneous switching noise through a switching current, whose properties and details are described. Thus, the results are discussed and performed using MATLAB and PSpice tools. It demonstrated that the presence of many cores in the same PCB influences the SSN due to electromagnetic coupling.
