The partial element equivalent circuit method (PEEC) has been popularly used for signal integrity and power integrity. Its port setup usually only includes conductive effects in the format of current sources or voltage sources. However, its radiation effect was neither included nor studied. In this paper, for the first time we provide novel solutions to approximate the radiation contributions from...
Proper power integrity analysis is required for printed circuit board (PCB) power distribution network (PDN) design. Developing a simple physics-based equivalent circuit model for critical structures is essential for understanding the physics of the system and for intelligent designs. In this paper, a physics-based model size reduction (PMSR) method is applied to get the equivalent circuit model for...
Surface current distribution provides an intuitive perspective on how the current flows, which is critical for high speed design. The surface current distribution for the power distribution network (PDN) in printed circuit board (PCB) is related to the input impedance observed by the IC looking into the PCB PDN. Two different principle methods are used to describe the current distribution, namely...
A hybrid approach to solve via impedance and model via transitions is presented in the paper. The method is a combination of via-plane capacitance extraction and the impedance matrices calculation of parallel plane pair. A new formulation of the integral equation method for axially symmetric geometry is used for the capacitance extraction. The method is validated with other model results.
