Hi Folks,
I am new to LTspice and trying to run a loop gain stability check on a fully differential amplifier. Thanks to this forum (especially Dave Zan), I managed to download an example amplifier with Dave Zan's balun.
When I implement the balun probe, and try to run the Tian method for Loop stability, results seem garbage.
Am I doing something silly? Why is the loop gain looks garbage? It is a simple circuit,
thanks!

Hi Folks,
Thanks to threads by Dave Zan and Sandrohv, I got the differential probe up and running!
I am new to this forum (edaboard.com was my old home). And I am impressed by so many discussions and mostly cordial conversations.
I basically created a subcircuit for a balun. Then using Sandrohv's beautiful LGS probe, connected it up correctly.
You may never see this, but thanks Dave Zan and Sandrohv! Much appreciated,
thanks!
