$\mu $ m CMOS 5 V process. It achieves a state-of-the-art total harmonic distortion plus noise (THD + N) of 0.00055% (−105.2 dB) and an FoM $_{\text {THD}\,+\,\text {N}}$ of 2119 while consuming a low quiescent current of 0.81 mA. Thanks to the wide-band-effective linearity enhancement, the THD + N across 20–20-kHz audio bandwidth is less than −100 dB.">
