Abstract:Subthreshold logic has become an attractive option in energy-constrained applications, where the key metric is energy consumption rather than operating speed or silicon area. However, the performance of circuits operating in the subthreshold region is extremely sensitive to the variations in the process, supply voltage, and temperature (PVT). Generally, circuit designers increase the clock period in order to reduce the timing failures, as well as to ensure the correct operations under all PVT conditions. Howev… 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.
