An Application of Self-Timed Circuits to the Reduction of Switching Noise in Analog-Digital Circuits

摘要

This paper presents an application where a self-timed approach reduces the switching noise in a mixed analog-digital circuit. Switching noise is of important concern in mixed signal systems, since it limits the performances of the analog part. Specifically, the digital core of an Analog to Digital converter has been designed following both a synchronous design style and another self-timed. Comparison between both versions shows the self-timed implementation reduce up to 50% the switching noise corresponding to the synchronous implementation.
