Investigation of the impact of parasitic parameters on PCB performance by hybridization of 3D quasistatic field solvers and MNA

This paper presents a hybrid approach to the investigation of the performance of printed circuit boards (PCB) by examining the impact of parasitic parameters of the board design on the efficiency of a device. First, parasitic parameters are extracted from the board layout by 3D quasistatic field solvers. Second, the corresponding equivalent circuit is constructed. Third, the extracted parasitic circuits are incorporated into functional circuit model. Finally, Modified Nodal Analysis (MNA) is used to examine a complete network. The hybridization makes it possible to vary circuit parameters and layout independently to achieve maximum system performance. Validation of the proposed method is performed by comparison of simulation results with measurements of GSM band signal amplifier.
