WitrynaIt’s one of the simplest possible op-amp circuits with closed-loop feedback. Even though a gain of 1 doesn’t give any voltage amplification, a buffer is extremely useful because it prevents one stage’s input impedance from loading the prior stage’s output impedance, which causes undesirable loss of signal transfer. Witryna14 maj 2024 · When the op amp output is at (nominally) 10 volts, the current through the diode string will be, as you realized, very close to zero. Then the op amp will have effectively no effect, and your analysis is correct. The answer sheet is wrong.
