Analog to digital converters (ADCs) enable the processing of real-world analog signals in the digital realm. These converters are widely used in sensor systems, medical components, multimedia systems, image sensors, and wireless sensor nodes. Today, in portable devices that are powered by batteries, low power consumption and small area are a major and important need. Therefore, methods that can reduce power consumption and area have a variety of applications and are of great importance. Power consumption is one of the most important features of an integrated analog to digital converter. In this paper, a new design of low-power and fast analog to digital converter is presented. This design is used for specific applications for image processing. The suggested approach for rereading the image for limited number of pixels was designed and simulated, showing a considerable power decrease compared to the suggested state that depends on the pixel values.
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.
