Abstract

An universal and programmable logic gate based on G4-FET technology is disclosed, leading to the design of more efficient logic circuits. A new full adder design based on the G4-FET is also presented. The G4-FET can also function as a unique router device offering coplanar crossing of signal paths that are isolated and perpendicular to one another. This has the potential of overcoming major limitations in VLSI design where complex interconnection schemes have become increasingly problematic.
