Abstract

For a space application in “push broom” remote sensing, with very large pixels for visible light and near-infrared detection at dusk, we reached out to a maximum light sensitivity by combining the largest possible pixel pitch, very high fill factor and high conversion gain. To increase the sensitivity further, we introduce a four-stage analog voltage domain TDI. The device is TID- and SEE-hard. It is manufactured in XFAB’s XS180nm CIS process. We present measured results on photoresponse, the speed of photocharge collection, the effect of TDI on read noise, and dynamic range.
