Abstract: Future energy harvesting systems require ultra-low supply sensor interfaces operating at sub-0.4 V. Time-based sensor-to-digital interfaces, though compatible with ultra-low supply, are highly sensitive to inherent mismatch in the current-controlled ring oscillators (CCRO) especially in… read more here.
