SIMULATION OF PROGRAMMABLE SINGLE-ELECTRON NANOCIRCUITS

Abstract

The speed and specializations of large-scale integrated circuits always contradict their versatility, which expands their range and causes the rise in price of electronic devices. It is possible to eliminate the contradictions between universality and specialization by developing programmable nanoelectronic devices, the algorithms of which are changed at the request of computer hardware developers, i.e. by creating arithmetic circuits with programmable characteristics. The development of issues of theory and practice of the majority principle is now an urgent problem, since the nanoelectronic execution of computer systems with programmable structures will significantly reduce their cost and significantly simplify the design stage of automated systems. Today there is an important problem of developing principles for building reliable computer equipment. The use of mathematical and circuit modeling along with computer-aided design systems (CAD) can significantly increase the reliability of the designed devices. The authors prove the advantages of creating programmable nanodevices to overcome the physical limitations of micro-rominiatization. This continuity contributes to the accelerated introduction of mathematical modeling based on programmable nanoelectronics devices. The simulation and computer-aided design of reliable programmable nanoelectronic devices based on the technology of quantum automata is described. While constructing single-electron nanocircuits of combinational and sequential types the theory of majority logic is used. The order of construction and programming of various types of arithmetic-logic units is analyzed.
