Summary :

A novel multiple-valued transfer gate (T-gate) consisting of multiple-junction surface tunnel transistors (MJSTTs) and hetero-junction FETs (HJFETs) was developed and its operation was confirmed by both simulation and experiment. The number of the devices required to form the T-gate can be drastically reduced because of the high functionality of the MJSTT; namely only three MJSTTs and three HJFETs are required to fabricate the three-valued T-gate. This number of transistors is less than half that of a conventional circuit. The fabricated circuit exhibited a basic T-gate operation with various logic functions. Furthermore, only one T-gate is needed to form a multiple-valued D-flip-flop (D-FF) circuit.
