Abstract

This work utilizes device-level eye-diagram measurements to examine NBTI-induced changes in timing jitter at circuit speeds. The measured jitter is examined for a variety of ring-oscillator and pseudo-random gate patterns. The ring-oscillator patterns were chosen to mimic typical NBTI reliability characterizations while the pseudo-random patterns act as an approximation for real world random logic. Our observations indicate that NBTI-induced jitter is gate pattern-dependent and most severe for the pseudo-random case. Collectively, this work strongly suggests that typical NBTI ring-oscillator characterization methods are insensitive to random logic timing jitter.
