介绍了一种由四个约瑟夫森结构成闭环的约瑟夫森逻辑门（4JL门）及其工作特性。器件采用铅合金技术制造，最小线宽为5µm。在完全输入/输出电流隔离的情况下，电流增益为2的门操作已经完成。在10个or门的链中测量到每个门20 ps的逻辑延迟，风扇输出为1，平均功耗为3.7 μ W。
A Josephson logic gate which consists of a closed loop with four Josephson junctions (4JL gate) and its operating characteristics are described. Devices have been fabricated using Pb-alloy technology with a minimum line-width of 5 µm. Gate operations with a current gain of 2 have been performed under complete input/output current isolation. A logic delay of 20 ps per gate has been measured in a chain of ten OR-gates for a fan-out of 1 with an average power dissipation of 3.7 µW.
