Abstract
This paper illustrates the impact of temporal degradations due to aging on current digital-to-analog converters (IDACs) within the context of a feed-forward equalizer (FFE) that is used in high-speed links. Aging causes mismatch in the current mirror, a matching-critical building block of IDACs, which degrades IDAC performance. The work analyzes and models the effect of mismatch over IDAC performance metrics and demonstrates how this affects FFE behavior. Finally, a novel scheme for FFE recalibration to recover from this degradation is presented.
