OPTIMIZED IMPLEMENTATION OF REVERSIBLE PRIORITY ENCODER USING NANO QCA

Quantum-dot cellular automata (QCA) is a possible replacement for complementary metal–oxide–semiconductor technology (CMOS). With the help of reversible computing, it is possible to attain zero power dissipation. The design of a reversible priority encoder based on QCA is proposed in this work. Peres and BJN gates are the design’s foundational elements. The QCA designer simulator verifies the suggested design. The performance analysis is implemented based on the simulation results. The proposed encoder reduces the amount of heat energy dissipation, producing quality data also solving the problem of the jumbled data. The proposed reversible circuit has the potential to be a game changer. Since reversible logic circuit provides zero information loss, it will be a key component in future wireless communication. The estimated energy dissipation of suggested QCA circuits is investigated, implying that QCA could be a suitable platform for implementation of Reversible circuits.
