ideal soueces in cadence virtuoso

[mirror_pole]

Hello guys,

I got a question concerning ideal sources in cadence. I build a circuit using ideal sources and want to replace them by real ones using transistors.
There is one current source which is not fixed to a rail and is therefore floating. It might sound stupid but can ideal sources have an impact on your poles?
My intention was that this floating current source which is not fixed provides a large parasitic impedance(ideal current source), so the pole assosiated with that node moves left in my bode plot.

Ideal current source is an open in the circuit. Moreover, every AC analysis replaces ideal sources with their internal impedances, so ac, PZ, stb analysis seeing open circuit in this place.
