However, the lack of resistance of QCA circuits under defects in previous works is a vital challenge affecting the stability of the circuit and output production. In addition, with the high defect rate in QCA, suggesting resistance and stable structures is critical. Furthermore, the 3input majority gate is a fundamental component of QCA circuits; therefore, improving this essential gate would enable the development of fault-tolerant circuits. This paper recommends a 3-input majority gate which is 100% fault-tolerant against single-cell omission defects. Moreover, the fundamental gates are introduced based on the proposed gate. In addition, an adder and a 1:2 decoder are also designed. Using QCADesigner 2.0.3 and QCAPro software, simulations of structures and analysis of power consumption are performed.eninfo:eu-repo/semantics/closedAccessFull-AdderFull-AdderCellular-AutomataDecoderError Probability ModelFull-AdderFault-tolerant 3-input majority gate (FTMG)Cellular-AutomataPower ConsumptionArticle110WOS:00104878930000110.1016/j.compeleceng.2023.1088652-s2.0-85166229431Q2Q1
