Summary :

Based on the similarity in current-voltage characteristics of resonant-tunneling diodes (RTDs) and tunneling-type superconductive Josephson junctions, novel current-mode logic circuits consisting of four RTDs have been proposed. NAND and NOR functions, as well as AND and OR, can be obtained in a simple circuit configuration. SPICE simulation showed that the present circuits can operate at a clock frequency as high as 200 GHz.
