Quantum Dot Cellular Automata is an emerging technology in the field of nanotechnology and has the potential to replace the existing CMOS technology. CMOS technology has its limitations in terms of high leakage current. However, QCA technology has higher speed of operation and very low power consumption. In this paper, designs for 2-4 and 3-8 decoder circuits have been made using a novel inverter circuit design which helps in decreasing the energy dissipation of the circuits. Finally, the proposed designs are compared to previously made designs. All the circuits in this paper have been simulated using QCA Designer software.

Keywords: QCA, decoders, laser ablation, majority voter, kink energy.
