This work presents a high-speed global shutter CMOS image sensor (CIS) designed for absorption imaging applications requiring high signal-to-noise ratio (SNR) under high illumination for detection of small light amount differences. In general, large full well capacity (FWC) reduces conversion gain (CG) and increases input-referred noise. This work proposes a two-stage lateral overflow integration capacitor (LOFIC) global shutter CIS featuring near-saturation-referred signal amplification dual pixel reset voltage and an in-column programmable gain amplifier (PGA) and multi-sampling to suppress input-referred noise electron. The fabricated CIS achieved 128dB dynamic range (DR) and 72.8 dB maximum SNR at 1000 fps. Imaging experiments of semiconductor manufacturing tool demonstrated clear visualization of minute concentration variations of NO2 gas, indicating suitability for high-speed absorption applications. |
