Hi,
I have a basic question related to EM simulations. (I am using ADS Momentum (ADS 2021) in Cadence Virtuoso (!C618) environment). I would like to EM simulate a 30 fF MOM cap. The way I am doing this is as follows:
I attach an input pin and an output pin. Define these as the input port and the output port. Perform EM simulations, and then measure capacitance using Y parameters.
My question is, do I need to attach 4 pins overall and use differential ports at the input and output? Is return current involved here? I am quite confused at what happens to the return path in a lumped component like a capacitor.
Thanks.
