Lorsque l'on considère le matériau entre la source et le drain, quels sont deux types fondamentaux de transistors à effet de champ (FET)?
- AGallium et arséniure
- BCanal N et canal P
- CNPN et PNP
- DSilicium et germanium
Correct answer: B — Canal N et canal P. Question tirée de la banque officielle d'ISDE.
Why
Field-effect transistors are sorted by the type of charge carriers flowing between the source and drain, which creates either an N channel or a P channel. The full explanation — and one for every question — is in Pro.
