<= I use this model for a (pseudo) real opamp.
What is the definition of "Input/output impedance" for this circuit? I mean, I suppose that for the input i could consider V_in/I_in . And what about the output resistance? Which currents I have to consider? Moreover, if I connect a load R_L to V_out what does it changes for this quantities defined above?
