I am using Momentum to design a differential inductor and then use it on my VCO design in ADS. The problem is when I insert my designed inductor to the VCO, the inductor blockes the transistors so that the simulation would temirnate due to not knowing the transistors model. Anyone has a solution or idea about this??
The circuit is working now. I can not describe why but I just copy and paste the inductor to another page and insert it to the circuit and suddenly starts working.
But thanks anyway.
