Abstract
Techniques are disclosed for systems and methods for facilitating pixel readout with partitioned analog-to-digital conversion. A device includes a detector, a capacitor coupled to the detector, a counter circuit coupled to the capacitor, a reset circuit coupled to the capacitor, and a processing circuit. The detector is configured to detect electromagnetic radiation associated with a scene and generate an associated detection signal. The capacitor is configured to, during an integration period, accumulate a voltage based on the detection signal. The counter circuit is configured to, during the integration period, adjust a counter value based on a comparison of the voltage and a reference voltage. The reset circuit is configured to, during the integration period, reset the capacitor based on the comparison. The processing circuit is configured to generate a digital detector output based on the counter value when the integration period has elapsed. Related methods are also provided.
