I am trying to measure the output impedance of an opamp in the attached configuration. Results are attached.
Basically, Zo = Vo/Io = 10mV/40mA = 0.25 Ohms.
Without the capacitor in the circuit, I get mostly a large dc current. Is there a better method to measure output impedance? I would like to verify my results.
