THE MONOLITHIC 14b D/A converter to be described has been found to achieve *l/2 LSB precision without trimming of analog components.In spite of the rapid progress of integrated circuit technology, the accuracy of a DAC, in its monolithic form, has been limited to 10b accuracy. Because of the inherent process variation of monolithic ICs, only recently. has it become possible to construct 12 and 13b DACs through the use of trimming techniques"2.An accurate DAC, with 14 to 16b linearity, is needed for high fidel…
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.
