Susceptibility of Integrated Circuits to RFI

This paper surveys the results of an extended research activity concerning the effects of radio frequency interference (RFI) on integrated circuits (IC's). Initially, the possible injection methods for conducted and radiated interference are presented, discussing their applicability and limitations. Then, the basic results of the susceptibility analysis of operational amplifiers and smart power integrated circuits are briefly discussed. Finally, experimental data describing some effects of RFI direct injection on switch mode power supply integrated controllers are presented.
