Detect V_plateau #2

Open fl4p opened 3 months ago

fl4p commented 3 months ago

Some datasheets display the V_plateau (miller plateau voltage) in the characteristics table. When V_plateau is missing, need to read it from the Gate Charge curve, see samples below.

The miller plateau exists for all inverting amplifiers with a (parasitic) feedback capacitor. For N-FETs Cgd will be push the gate voltage down during turn on.
