Abstract:A low-power coarse-fine time-to-digital converter (TDC) with a wide dynamic range and high time resolution is presented in this paper. The first stage is based on a buffer delayline chain. Then the input signal and its adjacent reference clock are injected into a Vernier-delay-line (VDL) time-quantizer at the second stage for a finer resolution. The proposed architecture can provide high resolution with less hardware compared to the one-stage VDL TDC with the same dynamic range. A powersaving circuit is employ… 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.
