Introducing a novel model based on particle wave duality for energy dissipation analysis in MQCA circuits

Abstract

In recent years, the limitations of the physical dimensions and high consumption of energy in electronic systems have been a major challenge. In order to decrease the physical size and energy consumption, various technologies have been investigated at the nano-scale. One of which is quantum cellular automata (QCA). This paper elaborates on the advantages of molecular QCA (MQCA) and proposes a new idea based on particle wave duality of free electron in QCA for energy dissipation analysis. The first stage is to calculate the dissipation of the internal dynamical and statically power of the cells considering the inner interaction of molecules. In return, by elaborating the inner calculation and consideration the distances and real size of the cells, energy dissipation values of MQCAs is calculated. Then, energy dissipation values for MQCA circuits consisting of binary wire and a majority gate are calculated. The achieved results show that in MQCA circuits, energy dissipation is very low. In addition, most of the energy dissipation in such circuits is related to the dynamical dissipation of the system. Our new concept proposes the separate use of classical physics and quantum mechanics properties in the calculation. Cell polarization changes simulated stage by stage based on current situation of electron and in each stage, the best conditions for calculations considered. The main innovation of this work is to introduce a new model based on particle wave duality for free electrons in MQCAs. In addition we presented equations to calculate total dissipation consisting dynamical and statically dissipation of MQCA circuits.
