Recently, Low power and reduced heat dissipation are an increasing demand for digital systems. Quantum Dot Cellular Automata (QCA) is a future generation solution based on nanotechnology for the digital systems. The QCA systems have advantages like the small size, ultralow power consumption and high switching frequency. The present research aims at introducing a novel three-input XOR gate containing 12 cells. The energy dissipation analysis of the proposed gate is verified using three different energy levels (γ=0.5Ek,γ=1.0,Ek andγ=1.5Εκ) at T = 2 Kelvin temperature. Simulation is performed for the proposed gate using QCA Designer tool version 2.0.3. The proposed three-input XOR gate has less number of cells, area and energy dissipation as compared to the previous structures. |
