    Hi, is tere a simple way for directly taking the values of the input output impedances of the built circuit on pspice?:confused:

    by the way also adding that I am looking for the output input impedance changing with the frequency.

    Yes, there is a simply way. Simply use ACsweep analysis and plot
    Zin = Vin/Iin ; Zout = Vout/Iout of Zout = (Vout_open
    _output, Rload = ∞) / ( Isc_output _short_currrent, Rload = 0)
