A swamped amplifier decreases input impedance and increases distortion.

Question

Quizplus · Accepted Answer

A swamped amplifier, by definition, uses a resistor in its emitter (for bipolar junction transistors) or source (for field-effect transistors) leg to stabilize its operating point and reduce variations due to temperature or transistor parameters. This configuration does not inherently decrease input impedance or increase distortion; instead, it aims to make the amplifier's performance more predictable and stable.
