In this brief, modeling and simulation of quadrature passive mixers are analyzed, focusing on the impact they have on the image rejection ratio (IRR). For this purpose, a 65-nm CMOS technology is used.
This work analyzes the effect of the most critical non-idealities on a passive polyphase filter implemented in a 65-nm CMOS technology, to attain single-sideband transmission in a 5 GHz Wi-Fi alike communication system. Non-idealities impact on this kind of passive complex filter have not been thoroughly analyzed in literature.
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.
