A 1:2:1 Josephson interferometer has been fabricated with small-area, high--current-density tunnel junctions. The short intrinsic RC times of these junctions result in device I-V characteristics with reduced hysteresis suitable for use in nonlatching logic circuits. The control current for this interferometer was fed directly, and asymmetrically, into the base electrode. Critical current versus control current measurements indicate that this device has a current gain greater than unity. The interferometer described represents an exploratory study of circuit design incorporating low-hysteresis junctions.
