Circuit-based description and modeling of electromagnetic noise effects in packaged low-power electronics

Abstract

A methodology is presented for the simulation of electromagnetic noise interactions in packaged low-power electronics using circuit-based models. The availability of such a methodology provides for a unified approach to the modeling of crosstalk, simultaneous switching noise, as well as all other types of noise interactions that impact signal integrity and component/system internal and external electromagnetic compatibility, using a simulation environment that is very compatible with existing circuit simulators such as SPICE. Illustrative examples from noise interactions in mixed-signal analog/digital circuits are used to demonstrate the unique capabilities of the proposed electromagnetic modeling methodology.
