Global Trends
• Trends toward less ICs
• Products consists of System-In-Package (SiP) or
System-on-chip (SoC)
• Products have to meet EMC requirement
• Ultimately system EMC will apply to ICs

Global Trends
EMC concerns rank 3rd position in IC design
1) Power integrity : Make sure
its is supplied properly
2) signal integrity : Make sure
it works properly
3) EMC :Make sure the IC is
compliant

•
•
•
•
Create a 15-years vision focused on ICs
Highlight issues and barriers to be resolved
Generate ideas for future research and projects
Attract national, European funding, research
grants
• Convince industry research and government
leaders

General information related to the EMC of ICs have been
given
Key topics on emission and susceptibility have been reviewed
Standard measurement approaches available for 3-10 GHz
bandwidth
From 10 to 40 GHz, only radiated mode approaches exist.
Key challenges : models and efficient methodologies for
reliable prediction above 3 GHz.
In the next years, pressure for low-emission and high
immunity should increase
This information should contribute to build a future EMC
roadmap for semiconductors
partnership with a regrouping of worldwide experts in the field
mandatory
