We investigate the influence of two important practical design parameters on total harmonic distortion (THD) for the design of low-voltage (0.9–1.4 V) low-power analog Class-D amplifiers: the linearity of the carrier waveform and the impedance of the output stage. We show that the carrier nonlineari...
