Recent work has shown that high-order single-bit sigma-delta modulators suffer from lowlevel artifacts such as idle tones and noise modulation. Techniques that have been proposed to reduce or eliminate these errors include the application of dither inside the one-bit quantiser loop, and selecting a loop filter which makes the modulator chaotic. This paper compares the efficacy of these two approaches by simulating high-resolution sigma-delta modulators suitable for audio-conversiondoi:10.1109/iscas.1995.521591 dblp:conf/iscas/DunnS95 fatcat:nl4sh73gmnerlbxvrvuomvis3y
