Question

Quizplus · Accepted Answer

A voltage follower, also known as a unity-gain amplifier or buffer amplifier, has a gain of one and identical input and output signals. This circuit has maximum bandwidth and is the ideal interface for transmitting high-impedance signals to a low-impedance load without any signal attenuation. The comparator, mixer, and differential amplifier circuits all have different gain levels and are not suitable for this purpose.
