International Technology Roadmap for Semiconductors (ITRS) set a road map for More than Moore (MtM). Where device is scaled more than what the moore’s law predicts. This MtM scaling will leads to substantially large design in the future and also huge power dissipation due to irreversible logic computation. Since applying low power technique has become tedious and time consuming. The solution is...

The ionic inputs to new fluorophore have been mimicked as a superimposed electronic molecular keypad lock and half-subtractor.

In recent years, reversible logic has emerged as a promising computing paradigm having application in low power CMOS, quantum computing, nanotechnology, and optical computing. The classical set of gates such as AND, OR, and EXOR are not reversible. In this paper, the authors have proposed reversible programmable logic array (RPLA) architecture using reversible Fredkin and Feynman gates. The pro...

A four port network adder-subtractor module, for surface plasmon polariton (SPP) waves based on a ring resonator filter is proposed. The functionality of module is achieved by the phase difference manipulation of guided SPPs through different arms connected to the ring resonator. The module is designed using the concepts of a basic two-port device proposed in this paper. It is shown that two po...

A new 1-bit full adder (FA) cell illustrating low-power, high-speed, and a small area is presented by combination of transmission gate (TG), pass transistor logic (PTL), float techniques. Using the proposed cell, 4:2 compressor implemented its performance investigated under diverse circumstances voltage, temperature, driving. The process corners are evaluated through process-voltage-temperature...

Reversible logic enables ultra-low power circuit design and quantum computation. Quantum-dot Cellular Automata (QCA) is the most promising technology considered to implement reversible circuits, mainly due correspondence between features of QCA circuits. This work aims push forward state-of-the-art QCA-based circuits implementation by proposing a novel full adder\full subtractor (FA\FS). At fir...

In this paper a novel design of all-optical half-subtractor based on nonlinear directional coupler is proposed.
