  • Abstract
    Aperture transformation reduces metastability by trading unsafe edge arrival times with control signal metastability. We improve this further by providing 1) a new runt-free Schmitt trigger-based hardening technique using a controlled clock signal and 2) a new detection/compensation technique that overwrites controlled-clock metastability using set&clear controls.
