Abstract:Conventional current-mode summation utilized in feed-forward equalization (FFE) has disadvantages in power consumption and linearity and thus becomes less attractive when high-speed low-power equalization is required. A Multi-Capacitor (MultiCap) structure is presented to overcome these disadvantages by supporting voltage-mode summation. This passive structure replaces the current-summation block of the transmit FFE and has zero power consumption. A set of equations are derived to estimate the useable value of… 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.
