  • Continuously self-calibrated latched comparator
    Patent number: 8836375
    Abstract: A comparator apparatus includes an amplifier and one or more latched comparators connected to the amplifier that compares input voltage signals to predefined reference voltage signals. The comparator apparatus includes an offset that limits the minimum input differential voltage signal with respect to the predefined voltage signals. A calibration component is electrically connected to the latched comparator and assists in continuously measuring and compensating the offset.
