It is very difficult to get a small output impedance with a
A) common-collector amplifier.
B) common-emitter amplifier.
C) common-base amplifier.
D) emitter-follower amplifier.

Question

Quizplus · Accepted Answer

A common-emitter amplifier typically has a higher output impedance compared to common-collector (emitter-follower) and common-base amplifiers, making it difficult to achieve a small output impedance with this configuration.
