In this fourth video on differential amplifiers, we remove nearly all
distortion from an amplifier's output by introducing negative feedback,
and successfully construct an amplifier with a low offset voltage, operation
all the way to DC, and a stable gain of approximately 10. We try to make
a nearly-perfect follower with the same circuit, and fail, because the
amplifier starts to oscillate when we configure it for unity gain.
For home gamers, schematics of the demo circuits are on the project GitHub:
