Abstract

This paper describes the effects of accumulated and independent clock jitters on the tonality and the Signal-to-Noise Ratio (SNR) of discrete-time delta-sigma modulators. Simulations demonstrate that accumulated clock jitter exhibits increased tonality in the magnitude spectrum of the delta-sigma modulator output especially at very high frequencies, while having no significant effect on the SNR. Independent clock jitter, on the other hand, degrades SNR performance but causes no increase in tonality.
