HYBRID PHOTO-SENSITIVE CIRCUIT Russian patent published in 1999 - IPC

FIELD: semiconductor electronics, in particular, design of multiple-unit photodetectors. SUBSTANCE: multiple-unit photodetector in hybrid photo-sensitive circuit is based on X-Y addressing. Each column is connected to corresponding channel of linear multiplexer which provides possibility to accumulate signal charges. In addition multiple-unit photodetector is equipped with additional layer, which is located between structure with quantum dips and lower conducting layer and has opposite conductance. This layer is electrically cut into strips which are continuous within range of each line and are connected to corresponding channels of line commutator. EFFECT: increased threshold sensitivity in conditions of increased background illumination. 2 dwg
