Transfer characteristics of Josephson interferometers made with nonhysteretic junctions can be improved using positive feedback. Numerical calculations show that an interferometer's continuous current transfer characteristic can be sharpened to a step function by sending some of the output current back through a control current path. Logic circuits using feedback should have fairly wide operating margins. In some configurations parallel fanout is possible.
