WebJul 19, 2024 · Why would it clip the negative voltage any more than it would clip the positive voltage. Ground has no polarity. The capacitor removes the dc bias at the output of the op amp so the capacitor output has a DC average of zero volts. For that to happen, the output waveform must equally go above and below ground, as you observed.
