A Low-power and low-noise digital pixel sensor (DPS) is presented in this paper. To design and analyze the random noise (RN) of the developed DPS, especially, we utilize a novel simulation method called transient-based AC noise simulation (TBAS) which can effectively help to estimate the noise components of the low-powered single-slope (SS) analog-to-digital converter (ADC).Based on this noise analysis, the high performance DPS has been successfully designed and demonstrated.
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.
