摘要
An apparatus can be used for detecting pile-up within circuitry associated with photodetectors. The apparatus includes an input terminal configured to receive a plurality of photodetector outputs. An OR-tree is coupled in parallel with the circuitry associated with the photodetectors. The OR-tree has an input coupled to the input terminal and is configured to combine the photodetector outputs. A counter is configured to count an output of the OR-tree. A comparator is configured to compare an output of the counter to a determined threshold value, wherein the comparator is configured to output an indicator indicating pile-up within the circuitry associated with photodetectors based on the output of the counter being greater than or equal to the determined threshold value.
