Demonstration of a novel multiple-valued T-gate usingmultiple-junction surface tunnel transistors and its application tothree-valued data flip-flop

摘要

A novel T-gate consisting of multi-junction surface tunneltransistors (MJ-STTs) and hetero-junction FETs (HJFETs) were proposedand its operation was successfully confirmed by both simulation andexperiment. The number of the devices required for their-gate can bedrastically reduced due to a high functionality of the MJ-STT. Onlythree MJ-STTs and three HJFETs were required to fabricate thethree-valued T-gate, whose number is less than one half of that of theconventional circuit. The fabricated circuit exhibited a basic T-gateoperation with various logic function. Furthermore, a multiple-valueddata flip-flop (D-FF) circuit could be realized by only one T-gate
