Abstract

This paper presents a detailed analysis of high-performanceedge-triggered memory elements for deep submicron mixed-signalapplications. The variations of the main parameters (power, delay,peak of supply current) with supply voltage, as well as timingrestrictions have been studied. Especial emphasis has been given toswitching-noise generation, an aspect of important concern inmixed-signal applications. We have analyzed the sources ofswitching noise, noticing that, the less noisy flip-flops are thosebased on differential structures.
