1. It seems that when you use PORT, you need to fill in voltage amplitude information in PORT's properties (psin). But circuit input (IN) is current driven, it this still applicatable? or do I need to add a 1Ω resistor in series with the port to convert voltage to current?
2. My output is fully differential (OUTP, OUTN), do we still need to add 2 ports at the output? or just need to add 1 (leaving the other port floating) ?
3. Do you have any tutorial/pdf/website which have details in how to measure S-parameters using Cadence?
do you have access to the cadence sourcelink? you can find there some examples. or you can find on edaboard a spectreRF manual, which has some examples.
