A Digital Requantizer With Shaped Requantization Noise That Remains Well Behaved After Nonlinear Distortion

A major problem in oversampling digital-to-analog converters and fractional-N frequency synthesizers, which are ubiquitous in modern communication systems, is that the noise they introduce contains spurious tones. The spurious tones are the result of digitally generated, quantized signals passing th...
