Image sensor assembly with data signal line for intensity readout

Abstract

An image sensor assembly includes pixel circuits, wherein each pixel circuit includes an amplifier transistor electrically coupled to a data signal line. A buffer transistor is electrically connected to the data signal line. The buffer transistor discharges the data signal line in an AD conversion period. The image sensor assembly further includes a detector circuit that includes a sensing path. The amplifier transistor, the buffer transistor, and the sensing path are electrically connected in series. The detector circuit outputs an active comparator output signal when a current through the sensing path exceeds a predefined threshold value.
