Fully differential amplifier simulation setup

FormerMember
FormerMember

Dear friends, 

It is the first time for me to design a fully differential amplifier and I don't know know most of the simulation setup,

I would like to ask you please to guide me for this simulations,

I would like to first ask you how to simulate the DC gain, GBW and Phase margin.

I heard that there is a Balun source in cadence which convert the single ended input to fully differential to provide the inputs of the amplifier with equal and out of phase signals.

Also I heard about stability simulation is better to extract these parameters using diffstbprobe.

I am looking forward for your help

Best Regards
