Dans un transistor à effet de champ (MOSFET) à appauvrissement avec canal N, la circulation des électrons est associée à :
- Al'enrichissement du canal Q
- Bl'appauvrissement du canal N
- Cl'appauvrissement du canal P
- Dl'enrichissement du canal P
Correct answer: B — l'appauvrissement du canal N. Question tirée de la banque officielle d'ISDE.
Why
In an n-channel depletion type MOSFET, the device naturally allows electrons to flow through a built-in n-type channel even when no voltage is applied to the gate. The full explanation — and one for every question — is in Pro.
