Summary :

A multiple-valued logic inverter is proposed that uses single-electron-tunneling (SET) circuits in which the discreteness of the electron charge is utilized. The inverter circuit, which is composed of only two SET transistors, has a memory function as well as an inverter function for multiple-valued logic. A quantizing circuit and a D flip-flop circuit for multiple-valued logic can be compactly constructed by combining two inverters. A threshold device can be compactly constructed by attaching more than one input capacitor to the inverter circuit. A quaternary full adder circuit can be constructed by using two threshold devices. Implementation issues are also discussed.
