PIXEL CIRCUIT FOR RADIATION DETECTION

摘要

The present invention relates to an on-pixel readout circuit for detectors, and more particularly to an active pixel sensor (APS) circuit for radiation detection, capable of providing stable and predictable on-pixel amplification in the presence o f device degradation and/or mismatch, and variation in environmental factors like temperature and mechanical strain. This invention is applicable to various detector technologies such as flat panel imagers, sensor arrays, x-ray detectors, CMOS cameras, et c.
