Abstract:A single-supply level shifter with an internal supply feedback loop, which can shift an input signal from the sub-threshold level to the above-threshold level, is presented in this paper. This level shifter has a wider voltage conversion, less transmission delay, higher energy efficiency, and more flexibility in the physical layout than those described in previous citations. The proposed level shifter can convert a 210-mV input signal into a 1.2-V output signal across process corners with a flexible physical l… 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.
