This article proposes a low-complexity frequency equalization technique for pulsewidth modulation (PWM)-residual-aliasing reduction in closed-loop Class-D audio amplifiers to achieve both low total harmonic distortion plus noise (THD+N) and low quies

In this letter, a soft-switching transformerless dc−dc converter with single-input bipolar symmetric outputs (SIBSO) is proposed, which has positive and negative outputs with equal voltage amplitude and can be used in audio amplifier, bipolar symme

Conventional half bridge class-D audio amplifier (HB-CDAA) systems typically suffer from serious bus-voltage pumping. Such a bus-voltage pumping increases the device stress and deteriorates the total harmonic distortion and noise (THD+N) of HB-CDAA.
