how to simulate the large siganl loop gain

Question asked by ARNE on Dec 5, 2005

Currently I am working on Dynamic Frequency divider and using ADS to perform the simulation. In
order to realize such a design, I have to display the large signal loop gain  at a defined point of the circuit vs the frequency for various input power . The loop gain should fulfill the oscillation condition (gain is greater than unity at the output frequency when the input power source is applied).

The problem is the following: If I use the tool Oscport2, I need to set the Injected voltage values. But in my case, I would like simply to display the
large signal loop gain at the oscport2 vs frequency for different input power (P1tone) without to configure this Vinjplan parameter. Is there any way to do this ?

If Oscport2 is not the right way for me to simulate the large signal loop gain with input source, anyone knows any other tools with which I could achieve such
as simulation.???
