Enhancement of Full Adder Using Single Electron Transistor

Abstract

For the next generation VLSI circuits with high density, the most efficient device that can be used in basic circuits is the Single electron devices because they consume very low power and the package density. Single electron transistor [SET] is a new evolution in nanotechnology. It can be scaled to a great extent almost to that of atomic scale. It has unique characteristics of controlling one electron at a time. In an SET the number of electrons involved in logic operations is very less. Hence, the power consumption also minimizes to a great extent. As the electrons are quantized, the operating speed is very high and finds its application in many VLSI circuits.
