Abstract:This paper describes critical circuit building blocks for emerging sensing applications, particularly those where volume, and therefore power consumption constraints are orders of magnitude below current state of the art. Developments in ultra-low power microprocessors and memories are described, along with sub-nW timekeeping circuits, pW voltage references, and efficient DC-DC voltage conversion circuits at sub-µA current loads. Taken together, these circuit design advances point to a vision of true mm 3 lowc… 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.
