Functional Loop Logic (FLL) is a logic concept adaptable to the Josephson technology and can be used to implement complex logic functions, such as adders, decoders and comparators. It is to be contrasted with random logic implementation which is based on interconnecting the three basic simple logic elements AND, 0R and INVERT in a random fashion. The following features are offered by FLL: (1) DC powered, (2) wide operating margins, (3) overdrive capability and hence speed, (4) single rail capability, (5) use of undamped interferometers, and (6) high density.
