The modern telecommunication services require increasingly wide tuning bands and improved spectral purity in order to support the growing demand for high data rate in the new generation wireless standards. The resulting VCOs have to deal with a difficult trade-off between wide tuning bandwidth and phase-noise. The paper introduces a new VCO architecture with a double tuning control, the former coarse to select the band the latter fine to precisely tune the frequency. The VCO is organized in an innovative distributed arrangement. Experimental results validating the theory are reported and discussed.
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.
