Efficient passive network description of IC conducted emission models for model reduction

摘要

This article adresses the model reduction of IC conducted emissionmodels. A method to efficiently deal with the high number ofindependent sources in IC conducted emission models, which are astrong limitation for model order reduction, is presented. A networkalteration is proposed, which allows for a much higher modelreduction than standard approaches. The system of the alterednetwork can be more efficiently reduced with standard model orderreduction algorithms in order to speed up frequency-simulations.Synthesising the reduced system into a passive electrical networkenables fast time-simulations to be made with circuit simulators.The whole procedure is validated by reducing an example of an ICconducted emission model of an 32 Bit microcontroller.
