Design of Reversible Decoder in the Quantum Cellular Automata (QCA) Technology

Abstract

MOSFET technology comes with a number of disadvantages, including tunneling and overheating. So researchers are looking for alternatives to MOSFET technology. One of these technologies is Quantum Cellular Automata Circuits (QCA), which offers a new method for calculating nanotechnology. Also, given the growing importance of reducing energy consumption, the use of reversible logic in QCA technology is a new issue. One way to solve the power loss problem is to design the circuits in a reversible manner. Circuit design using reversible gates ensures that the circuit does not waste energy. And by using fault tolerance mechanisms, it prevents bit errors. In this paper, the reversible decoder was designed and simulated using QCA Designer software. Due to the main property of reversible circuits, power consumption is also reduced. And by using fault tolerance mechanisms, it prevents bit errors.
