The FET amplifier common drain circuit is similar to which of the following bipolar transistor amplifier circuits?
- ACommon base
- BCommon mode
- CCommon collector
- DCommon emitter
Correct answer: C — Common collector. From the official ISED question bank, verified word for word.
Why
A common drain FET amplifier takes its output from the source, which follows the input voltage closely, just as a common collector bipolar circuit takes its output from the emitter to follow the input. The full explanation — and one for every question — is in Pro.
