ABSTRACT:
A superconductive logic device incorporating at least one Josephson junction comprises two superconductive electrodes, that is, a base electrode and a counter electrode with a thin insulating layer therebetween. The counter electrode has an extension for receiving an input signal and another extension connected to a ground plane. The input signal current which is supplied from the counter electrode to the ground plane acts on the Josephson junction with a magnetic field, while, a bias current is supplied from the base electrode and flows through the Josephson junction to the ground plane.
