グリーン関数法によるパッケージされたLSIの電流分布推定に関する検討

抄録

In this study, we focused on high frequency currents on LSI. We estimated the high-frequency current distribution on a packaged LSI using the Green's Function method, in which the distribution of current is estimated by a two-dimensional magnetic field as an inverse problem. We used a packaged IC mounted on the PCB and estimated the current distribution on the packaged IC. As a result, we could observe the high-frequency current distribution on the packaged IC and the in- and outflow currents of the packaged IC as emission sources.
