Radiated emission analysis of power bus noise by using a power current model of an LSI

摘要

In this paper, a power current model of an LSI was used for analysis of radiated emissions. The simulated radiation noise was compared with measurements by using an evaluation module that emulates an LSI. The simulation results showed good agreement with the measurement results. The effects of adding an internal decoupling capacitance and/or internal decoupling inductance to an LSI were also evaluated.
