Abstract

Because of its high-speed properties and low power-dissipation, the Josephson junction digital integrated circuits (JJ IC) have been intensively investigated especially for applications in high performance digital systems. The high-speed properties of the JJ IC can be attributed to the quantum-effect-dominating switching speed as well as the light-velocity signal transmission between gates. A wide gate operation margin, multiple logic function capability, and a small gate size are among other important factors in the evaluation of the JJ logic gates. The small gate size is, in particular, very important because it make it possible to densely pack the logic gates and to shorten the signal transmission line length.
