WebThe men in white coats refer to this circuit as a cathode follower stage but it’s also commonly known as a ‘buffer’. This is because the circuit has high input impedance and low output impedance meaning it can effectively isolate or buffer one part of an audio circuit from another to prevent loading. WebⅠ What is a Voltage Follower? An op-amp circuit is a voltage follower (also called a unity-gain amplifier, a buffer amplifier, and an isolation amplifier).This suggests that the op-amp would not supply the signal with any enhancement. The explanation that it is called a voltage follower is because the output voltage matches the input voltage directly, which means … datawatch systems client toolsWebA quick sketchplanation for why you might want to use a voltage buffer in your circuit. dataweave cheat sheet

"Op-amp implementation A unity gain buffer amplifier may be constructed by applying a full series negative feedback (Fig. 2) to an op-amp simply by connecting its output to its inverting input, and connecting the signal source to the non-inverting input (Fig. 3).
