A novel ternary logic circuit using Josephson junction

A novel Josephson complementary ternary logic (JCTL) circuit is described. This fundamental circuit is based on the combination of two SQUIDs (superconducting quantum interference devices), one of which is switched in the positive direction and the other in the negative direction. The JCTL can perform the fundamental operations of AND, OR, NOT, and Double NOT in ternary form. The principle of the operation and design criteria are described in detail. Simulation results show that reliable operation of these circuits can be achieved with a high performance.<>
