4- Conclusion

EMI filter are designed to suppress EMI and RFI noises and are also used to protect sensitive systems

against electro-static discharges. The use of an Z-R-Z structure provides a very stable voltage on the

output during ESD discharge when layout has been correctly routed.

RF measurement must be done carefully after using calibration board provided with EMIF demoboards.

EMI filters on flipchip are the most efficient topology to filter and protect integrated circuit by saving PCB

area.
