PROJECT TITLE :

Energy dissipation of quantum-dot cellular automata logic gates - 2016

ABSTRACT:

Quantum-dot cellular automata (QCA) could be a new paradigm in nanoelectronics, where binary info is represented by charge configuration in cells. Ideal QCA logic gates are regarded as dissipationless, since there is no intercell charge transfer and no current flows out of cells. This work presents that these gates dissipate energy and compare energy consumptions of typical QCA logic gates in electrostatic and thermodynamic approaches. The results show that increasing the amount of inputs, concentration of the geometry and also the unbalanced numbers of 'zero' and '1' output states in the gate's truth table augment the energy dissipation of a QCA gate.
