In this paper a novel design of all-optical half-subtractor based on nonlinear directional coupler is proposed. By using four waveguides and appropriately adjusting the refractive indices and selecting the proper length of waveguides, halfsubtractor function can be obtained. The operation of this function is simulated by RSoft CAD-Layout (BeamPROP) simulator. The simulation results confirm the ...

This study introduces an optical DNA-based logic circuit that mimics a half-subtractor. The system contains an Au-surface immobilized molecular-beacon molecule that serves as a dual-gate molecule and outputs two series of fluorescence signals following Boolean INH and XOR patterns after interacting with one or two single-stranded DNA molecules as input. To the best of our knowledge, the system ...

Reversible logic circuits have emerged as a promising technology having its applications in low power CMOS, Quantum Computing, nanotechnology, and optical computing. Power is the major constraint for any circuit Each circuit demands not only low power, but fast speed. This paper is focused on the efficient design of the full Adder/Subtractor with the help of half adder subtractor with single co...

In this paper we are presenting a Half-Subtractor using Adaptive Voltage Level (AVL) technique consuming less power than the conventional one .The main objective is to design that half subtractor using either of the two adaptive voltage level(AVL) techniques to reduce the sub threshold leakage current which plays a very important role in the reduction of power dissipation. We can bring down the...

This work demonstrates two DNA-based logic circuits that behave as a half-adder and a half-subtractor. A half-adder is composed of an AND gate and an XOR gate, whereas a half-subtractor consists of an INH gate and an XOR gate. The proposed designs are inspired by molecular beacons.
