A method to estimate the frequency spectrum of IC power supply by measuring transient voltage on Power Distribution Network (PDN) was proposed in this work. The proposed method was validated through measurement on a testing board with three clock driver ICs. The result show good agreement between the estimated current spectrum and measured current spectrum at the major spikes.
A method on developing pre-layout PDN model utilizing 3D full-wave simulation was proposed in this work. The proposed method divides the PDN into different blocks and obtains the network parameters of each block using 3D full-wave simulation. The proposed method was validated with post-layout simulation. Results show that PDN impedance obtained from pre-layout PDN model developed using proposed method...
For safety reasons, design specifications of automotive electronics, as compared to consumer electronics, are more stringent and complex. With increasing demand for high-end graphical displays in commercial vehicles, good power distribution network (PDN) design is critical to ensure the reliable operation of the circuits. This paper describes a systematic PDN design method of a high-speed printed...
