Resonance properties of power supply and ground distribution networks in SoC

In this work, we propose a method for power grid modeling, where the grid consists of segments, which are regarded as transmission lines. The proposed approach allows the entire periodic power grid network to be represented for high-frequency AC simulations by only a small part of the power grid, terminated by impedance elements, equivalent to the impedance of the following power grid. The model performance has proved to be appropriate since the results correlate well with experimental results obtained from a 90 nm CMOS technology chip.
