Quantum-dot cellular automata (QCA) provide a novel electronics paradigm for information processing and communication.A basic quantum-dot cell consists of several quantum dots with two excess electrons.A binary coded decimal (BCD) and a decimal coded binary (DCB) circuit based on QCA logic gates: the and-or-inverter (AOI) gates are proposed in the study.In addition, the circuits designed by traditional CMOS technology are also implemented for comparison.Compare with the traditional CMOS BCD device, QCA circuit is a low power and area-efficient architecture.
