I tried to make a NOT gate with N type mosfet and everything seemed good when the gate had voltage, however I found strange things when the gate was open and that I put test components between the source and drain.
My voltmeter indicates a voltage of 1.8V between drain-ground, but a voltage of 1.6V between drain-source, even if nothing is going on at the gate. Then, I expected to have the remaining 0.2V at the 1M test resistor and/or parallel led I put between source-ground, but both were indicating 0V.
What am I missing ?
This mosfet's order is: gate, drain, source.
