Hi, i have a problem plotting Q in cadence.
I made a passband filter with an active inductor. I simulate s-parameters in spectre simulator
I assume that quality factor Q is equal to = imag(aaSP(2 1))/real(aaSP(2 1)) when i plotted i obtein a sort of bell like the response of a typical bandpass filter.

My question is i assume wrong the value of Q ? and i should be simulate my circuit in SpectreS.
The version of cadence i use is
Cadence version 5.10.41.500.3.49
Process c35b4
HIT kit 3.70.17.05
