A source follower is the MOSFET counterpart of which BJT amplifier configuration?

  • ACommon collector
  • BCommon emitter
  • CCommon base
  • DDifferential pair only
Report an error
Correct Answer: A. Common collector
Explanation: The common-drain MOSFET stage, or source follower, provides non-inverting voltage buffering similar to a BJT emitter follower/common-collector stage.
Reference: Standard analog electronics: source follower
