This paper demonstrates the design and layout of novel controlled inverter using majority gate based on Quantum Dot Cellular Automata with minimum complexity in comparisons to previous designs. The stability of the circuit has been determined by calculating the kink energy. The simulation results are captured and verified using QCA Designer tool.
