Hello all,
Probably a stupid question, but I don't see how I can do to solve it...
I would want to know how I can do to check the operating point of a protection schottky diode (placed in parallel with a sensor). In fact I would want to know the influence of the diode to reduce its effect (non linearity) on my sensor (which could be considered as a resistor).
How can I do to know the current (or voltage) in it ? If I try to evaluate the current in it, I have to make the assumption that the diode is forward biased and take a voltage on the curve to deduce the current in my circuit... how can I do to calculate it (operating point) without making assumption like this ?
See the schematic below
