Abstract:Current mode image sensors enable an easy implementation of focal plane algebraic functions, but suffer from poor linearity performance. A theoretical analysis is first performed on the source of the non-linearity for current mode image sensors. According to the analysis, an architecture of a current mode image sensor with a voltage feedback loop between pixel output and the current conveyor for linearity enhancement is proposed. An image sensor array of 100 × 200 current mode pixels is fabricated in 0.5um 2P3… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
