Abstract

This paper presents the modelling and analysis of electromagnetic interferences (EMI) for a 32-bit digital signal controller (DSC) that enables uncompromising performance and real-time control applications for high electromagnetic compatibility (EMC) requirement. The EMI behaviour model of the DSC for conducted emission, built upon the package and chip dies, is used to predict the EM emissions of the chip and printed circuit board (PCB) levels. The characterization of EMI has been analyzed by circuital simulations and conducted emission measurements according to the EMC model. It is successfully demonstrated that the simulated results are consistent with the predictions generated by using the proposed model. And the DSCs chip model, simulation and measurement of the EMI are necessary for the analysis, prediction, and compatibility of the PCB and systems design.
