Abstract
A high-fill factor/high-SNR CMOS readout integrated circuit (ROIC) array is designed for high dynamic range infrared imaging systems. The designed ROIC array uses a single reference photodiode that is routed to each unit cell in the array to subtract the dark current for high SNR and high fill factor. The achieved average SNR is 80 dB and the fill factor is 28% with a 25 x 25 μm2 unit cell size. With this new unit cell and routing approach, the size of the unit cell is reduced by 300% compared to other high SNR circuits. The maximum power consumption per unit pixel is 500nW.
