An unbypassed emitter resistor in a common-emitter amplifier generally causes the voltage gain magnitude to?

  • AIncrease without limit
  • BDecrease while improving linearity
  • CRemain exactly unchanged
  • DBecome exactly unity in every case
Report an error
Correct Answer: B. Decrease while improving linearity
Explanation: Emitter degeneration introduces local negative feedback, reducing gain but improving linearity and bias stability.
Reference: Standard analog electronics: emitter degeneration
