A four-valued logic full adder accepts two four-valued inputs and a binary carry input and produces a two-quaternary-digit, base-four, output word that is the sum of the values of the inputs. In this paper we present two new current-mode logic realizations of the four-valued logic full adder. Also reviewed is a recent I<supscrpt>2</supscrpt>L realization of(More)
Modern large-scale-integrated (LSI) digital circuit design philosophy is approaching a technological crossroad. Improvements in photomasking and surface processing technologies have significantly improved the yield on very large (&gt;40,000 mil<supscrpt>2</supscrpt>, &gt;5,000 devices) chips. But even with these contributions, a majority of LSI chip designs(More)
