摘要：

A prototype of a new high dynamic range readout scheme targeted for 3D-IC IR focal plane arrays is described. Dynamic range is extended using synchronous self-reset while high SNR is maintained using few non-uniformly spaced captures and least-squares fit to estimate pixel photocurrent. The prototype comprises of a 16x5 readout pixel array fabricated in a 0.18 mu m CMOS process and achieves 138dB dynamic range and 60dB peak SNR at 1000 frames/sec with energy consumption of 25.5nJ per pixel readout.
