AB  - A novel analogue class-D amplifier has been developed which produces low distortion. The structure follows the well known prior-art class-D structures with negative feedback, but includes modulation of the symmetry of the carrier oscillator waveform by a derivative of the input signal. This compensates a nonlinear phase modulation effect that is intrinsic to the prior-art structures. The improvement is substantial at very low extra cost.
