Abstract

This article describes a Josephson interferometer employing direct signal injection and magnetic coupling, e.g., as negative feedback, of the input signals to the interferometer loop. This results in a steep slope threshold characteristic permitting high input signal tolerances and makes the interferometer particularly suited for logic circuitry. The concept demonstrated for the specific example of an asymmetric 2-junction interferometer is applicable to any multi-junction interferometer structure.
