Novel BCD Circuits Design Using And-Or-Inverter Gate and Its Quantum-Dot Cellular Automata Implementation

چکیده
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.
