OpAmp Open Loop Stability Analysis with Pspice

I have the urgent need for analysis of the stability of an operational amplifier cuiruit with feedback. For that purpose I would like the AC analysis the open loop response of the operational amplifier circuit in order to determine the phase reserve and amplitude reserve. How can I use Pspice to analyse the open loop transfer function? At which circuit point must I introduce the AC source for correct open loop simulation?


Thanks in advance!
