I added a circuit that adds AC signal with Magnitude of 25 mV a variable DC signal between 0 to 5 using with op amp, and applied to a diode. I will measure the AC current through the diode with a lock in amplifier. I will use lock in amplifier built in function generator and auxillary output port behind it. From this experimental setup how can I measure C-V current of a reverse biased diode.
