Abstract:In recent years, inverter-based sigma-delta ( ) modulators have received great attention as a suitable approach for the design of low-voltage, low-power, switched-capacitor . This method uses digital inverters as the active elements to construct the integrators in the loop. In some applications, a reduced silicon area implementation is an important constraint; this demands the use of only one inverter in the integrator. This paper proposes to use the common-source amplifier as the building block to achieve the… 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.
