Low noise WDR ROIC for InGaAs SWIR image sensor
Author(s): Yang Ni

Paper Abstract

Hybridized image sensors are actually the only solution for image sensing beyond the spectral response of silicon devices. By hybridization, we can combine the best sensing material and photo-detector design with high performance CMOS readout circuitry. In the infrared band, we are facing typically 2 configurations: high background situation and low background situation. The performance of high background sensors are conditioned mainly by the integration capacity in each pixel which is the case for mid-wave and long-wave infrared detectors. For low background situation, the detector’s performance is mainly limited by the pixel’s noise performance which is conditioned by dark signal and readout noise. In the case of reflection based imaging condition, the pixel’s dynamic range is also an important parameter. This is the case for SWIR band imaging. We are particularly interested by InGaAs based SWIR image sensors.
