Characterization and modelling of EMI susceptibility in integrated circuits at high frequency

Abstract

In this paper an alternative method for characterizing and modelling the EMI susceptibility in integrated circuits at frequencies above 1 GHz is presented. The PCB layout design is focused on the optimization of the impedance mismatch losses on the radio frequency interference injection path. The PCB has been tested with several commercial operational amplifiers and the methodology is validated through both electrical transmission line simulations and electromagnetic cosimulations.
