Quel nom donne-t-on au circuit d'amplification composé d'un transistor à effet de champ ("FET") dont la source est asservie ("source follower")?
- ACircuit à mode commun
- BCircuit à porte commune
- CCircuit à drain commun
- DCircuit à source commune
Correct answer: C — Circuit à drain commun. Question tirée de la banque officielle d'ISDE.
Why
In a source follower, the input signal enters the gate and the output leaves the source, meaning the drain terminal connects to the power supply and stays at a steady voltage for both input and output. The full explanation — and one for every question — is in Pro.
