Negative feedback in an amplifier generally tends to?

  • AIncrease gain sensitivity to device variations
  • BReduce bandwidth
  • CImprove gain stability and increase bandwidth
  • DForce the amplifier into saturation
Report an error
Correct Answer: C. Improve gain stability and increase bandwidth
Explanation: Negative feedback normally reduces closed-loop gain but improves stability, linearity and bandwidth.
Reference: Standard analog electronics: negative feedback
