Technical noise modelling PCB

Please login with a confirmed email address before reporting spam

Dear community,

I am currently using COMSOL 5.2a. I need to do technical noise modelling of a PCB. I did not find any examples or tutorials, which might help me apart from the microstrip_line_crosstalk.mph example, which I cannot run on COMSOL 5.2.

More specifically, I need to model: - Crosstalk - 1/f noise - Thermal noise - Bouncing - Ringing - Impedance mismatching … on a PCB.

I don’t have much experience on this, so I need support. Best would be to have state-of-the-art models, which include all or some of these phenomena in order that I can base on them for my further models.

Thank you very much, Maria

Hi,

Here is a comsol blog post that has some of what you want to analyze:

https://www.comsol.com/blogs/analyzing-time-domain-reflectometry-for-2-electrical-designs/

Also, search around a bit more on their blog as sometimes there are some pieces here and there. If you are running an older version of comsol and are not on support it might be difficult to get simulation files.
