A voltage follower _____________?
Correct answer: D. has all of these
- A. has a voltage gain of 1
- B. is noninverting
- C. has no feedback resistor
- D. has all of these
Explanation
A voltage follower uses 100% negative feedback, giving a closed-loop voltage gain of approximately 1 without phase inversion. Its output is connected directly to the inverting input, so no separate feedback resistor is needed.
