System for pixel readout with partitioned analog-to-digital conversion

A system for pixel readout with partitioned analog-to-digital conversion is provided. An apparatus for detection includes a detector, a capacitor coupled with the detector, a counter circuit coupled with the capacitor, a reset circuit coupled with the capacitor, and a processing circuit. The detector is configured to detect electromagnetic radiation associated with the scene and generate an associated detection signal. The capacitor is configured to accumulate a voltage based on the detection signal during the integration period. The counter circuit is configured to adjust a counter value based on a comparison of the voltage and a reference voltage during the integration period. The reset circuit is configured to reset the capacitor based on the comparison during the integration period. The processing circuit is configured to generate a digital detector output based on the counter value when the integration period has elapsed. 提供了具有分区式模拟到数字转换的像素读出的系统。一种用于检测的装置包括检测器、与检测器耦合的电容器、与电容器耦合的计数器电路、与电容器耦合的重置电路以及处理电路。检测
