Abstract

The present invention relates to a flexible multifunctional logic circuit which switches a current direction to a serial or parallel direction using at least two single electron transistors (SETs) having the same pattern and as many field effect transistors (FETs) as the number of the single electron transistors and performs operations on multvalued signals using Coulomb oscillation that is the unique characteristic of SET to enable conversion of a single logic circuit to four basic logic circuits of NAND, OR, NOR and AND gates and a device using the same.

Description

technical field [0001] The present invention relates to a kind of flexible multifunctional logic circuit and the device using this circuit, and more particularly, relates to a method by using at least two single-electron transistors (SET) with the same pattern (pattern) and the same number as the single-electron transistors Multiple Field Effect Transistors (FETs) to convert the current direction to series or parallel direction, and use Coulomb oscillation (Coulomb oscillation) which is a characteristic of SET to perform operations on multi-valued signals to enable single logic circuits to NAND, A flexible multifunctional logic circuit for conversion of four basic logic circuits of OR, NOR, and AND gate, and a device using the flexible multifunctional logic circuit. Background technique [0002] In general, approaches to nanotechnology can be divided into top-down and bottom-up approaches. The top-down approach is a technique for gradually reducing the size of materials or ...
