Recent trends in 5G and radar systems have revealed the need for high-frequency DACs with minimal spurious emissions. Amplitude and timing errors in the DAC have proven to be a significant hindrance to linearity performance and have an increasing impact with frequency. Primary contributors to these errors are impedance mismatches in the current combining network as well as device mismatches.
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.
