Abstract

A novel complementary ternary logic circuit using Josephson junctions as switching gates is described. The principle of the circuit is based on the tristate of a Josephson junction, that is the state of switching in either positive direction or negative direction, in addition to the state of no switching. The JCTL is constructed of two SQUIDs (superconducting quantum interference devices), one of which is switched in the positive directions and the other in the negative direction. The JCTL can perform the fundamental operations of AND, OR, and NOT in ternary form and can function as a full adder if the voltage-current characteristics of the two SQUIDs are adjusted appropriately. The advantage of the JCTL is its higher speed of operation with higher density than the conventional Josephson binary logic circuit. The principle of operation is described in detail, and simulation results are presented.<>
