Noise in self-timed and synchronous implementations of a DSP

Abstract

This paper proposes the use of self-timed design as an elegant and cost effective solution to control noise. The importance of reducing the high frequency components of the switched current is demonstrated from a review of noise sources in electronic systems. The paper includes a comparison between synchronous and self-timed systems based on the implementation of a DSP and clearly demonstrates the benefits of self-timed design.
