THE INCREASING USE of MOS technology for the realization of analog circuit functions has led to the development of MOS circuit building blocks such as filters, voltage references, and operational amplifiers. One building block that has long been used in bipolar circuits is the 4-quadrant analog multiplier. However, analog multipliers with performance adequate for signal processing use have not previously been reported in MOS technology. This paper will report on an MOS analog multiplier, fabricated in standar…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
