Abstract:
In this paper, the research about m easurem ent and ana ly sis of conduc tive EM I no ise source has been done. F irst, the EM I no ise generation m echan ism of no ise source and com par ison between var ious modeling approaches are ana lyzed. Then, som e no ise source modeling m ethods such as resonant m ethod, insertion loss m ethod and two current probem e thod are discussed respective ly. Add itiona lly, the interna l impedance measurem en t and param eter ex traction of practica l no ise source is im plem ented by us ing two current probem e thod. Result is basica lly agreed w ith the m easurem ent resu lt by using impedance analyzer. The study in this paper may o ffer some use fu l in fo rm ation for conductive EM I filter design.
