摘要
A sigma-delta class-D amplifier includes a quantizer to quantize an input to produce a digital signal, and an output stage to produce an output according to the digital signal. The quantizer has a smaller step size so that the digital signal has at least five logical levels, and the sigma-delta class-D amplifier is thus improved to have wider stable modulation range and less switching loss.
