Topic: Analog Circuits

With the introduction of negative feedback, the gain-bandwidth product of an amplifier?

  • A. Becomes infinity
  • B. Increases
  • C. Decreases
  • D. Remains constant

Answer: D. Remains constant

Explanation: With negative feedback, the gain of the system decreases and the bandwidth increases by the same factor $(1+A\beta)$, but the overall gain-bandwidth product remains constant.
