Title: ccvs in Cadence
Post by ggnhdk on Jun 7^th, 2008, 10:35am

hello, I don't understand how to use Current control voltage source and current control current source on Cadence. For the CCVS it seems like a vdc with a transresistance to specify in the properties but I dont know which current it uses. How do I connect it to the circuit ? Which wire will it use for the current control?

Thanks for your help guys.

An current controlled source has to be told what current controls it. You do that by inserting a vdc with zero volts in series with the current you want to sense. Then when you insert the controlled source, you point it to the zero volt vdc. The thing to watch out for is when you cut and paste the combination, the reference designator of the vdc will change and you have to remember to point the controlled source to the new current probe.
