Towards Designing Optimized Low Power Reversible Demultiplexer for Emerging Nanocircuits
Lafifa Jamal, Md. Riaz Uddin · 2018
Reversible Logic plays a vital role in the field of nanotechnology and quantum computing. One of the most challenging issues in circuit design is power consumption. Reversible logic is one of the ways to optimize power consumption. This paper presents an efficient approach for designing optimized reversible demultiplexer which consumes less power. A generalized approach is proposed to design 1-to -n reversible demultiplexer. Theorem on the numbers of gates, garbage outputs and quantum cost has been presented. The comparative results show that the proposed design is much better than the existing designs in terms of garbage outputs, gate counts and quantum cost. The proposed reversible demultiplexer also requires less power and less area than existing demultiplexers. The proposed design is simulated in DSCH 3.5 software which verifies the correctness of the proposed circuit.
