Long wire EMI problems

Other Parts Discussed in Thread: FDC2214

Hi,

I am developing a capacitive sensor using the FDC2214 EVM. Unfortunately I am having EMI issues due to the long wires I need to use. The sensor pickup some interfecences when I am using the computer that powers the board.

The question is about how to place a common-mode choke, as suggested on FDC2214 datasheet. Do I have to take out the two resistors of one channel and replace them with one choke?

Thank you in advance.
