  • Abstract
    This paper presents a novel design for a Digital Delta Sigma Modulator (DDSM) which produces a spur-free spectrum for all constant inputs with higher order shaped additive LSB dither. We can increase the order of noise shaping of the applied dither to that of the modulator without any spurious tones appearing in the spectrum. The result is confirmed by simulation.
