Title: common mode noise.
Post by smarty on Jun 7^th, 2007, 10:16am

Hi,
I am working on high speed receiver. I am simulating the differential receiver for performance.
I would like to test the receiver by injecting AC common mode noise of 150mv(peak) on the inputs.

Could anybody suggest as to how I can make this setup in my simulation to inject this noise?.

Thanks and Regards,
SBR

Smarty,

If you have access to ADE, then why don't you try using the
ideal_balun. It allows you to independently input a common-
mode signal and differential-mode signal and generate
differential outputs. The implementation is discussed in Ken's
book, "The Designer's Guide to SPICE and Spectre".

Best Regards,

Sheldon
