An innovative methodology for evaluating multi-chip EMC in advanced 3G mobile platforms

This paper presents an innovative approach which consists in emulating the behavior of a disruptive chip, by means of a specific probe, and analyzing the risks of interference with the victim component. Chip-to-chip interferences may be investigated without requiring any specific EMC test board. Details of this methodology are provided and illustrated in the case of a 3G mobile platform. Valuable information about the sensitive zones, coupling orientation and critical coupling distances are extracted easily using this approach.
