Abstract
A system to convert between analog and digital signals, in some embodiments, comprises: a differentiator to produce a differentiated signal based on an input signal and a feedback signal; an integrator, coupled to the differentiator, to integrate the differentiated signal; a quantizer, coupled to the integrator, to quantize the integrated signal; and a low-pass feedback filter, coupled between an output of the quantizer and an input of the differentiator, to generate said feedback signal using the quantized signal, wherein the low-pass feedback filter pushes at least some noise of the quantized signal downward in the frequency spectrum.
