Calculate Is from the Vo values of your lab experiment. Then take the mean value of these Is values. This is the Is value of your individual 1N4148 diode. And that is what I meant with calibration in my answer above.... but I don't know Is
Yes. If you use diodes from the same lot, their Is values should be quite similar.So I have to mount the circuit and then calculate the Is from my lab results and using the formula. This circuit is going to be used to create TRUE-RMS altern-continous converter and I'll create more than one, so I have to calibrate each one.
No, just consider the temperature in the Vt = kT/q term.Each time I want to use one of these circuits will I have to calibrate it again?
Not with this simple circuit, I think. If you want to be independent of individual diode properties, you'd want to use a more complex circuit like one of those from the NS Application Note mentioned by FvM above. Moreover, this would give you temperature compensation.Is it strictly necessary to do it, I mean calibration of the circuit to find the Is or there are other ways?
