Molecular beacon-based half-adder and half-subtractor.
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.
متن کاملHigh-Speed Ternary Half adder based on GNRFET
Superior electronic properties of graphene make it a substitute candidate for beyond-CMOSnanoelectronics in electronic devices such as the field-effect transistors (FETs), tunnel barriers, andquantum dots. The armchair-edge graphene nanoribbons (AGNRs), which have semiconductor behavior,are used to design the digital circuits. This paper presents a new design of ternary half a...
متن کاملAll optical integrated full adder-subtractor and demultiplexer using SOA-based Mach– Zehnder interferometer
By exploiting nonlinear effects in a semiconductor optical amplifier, different functionalities for all-optical digital signal processing are implemented. In particular we demonstrate the logic functions of integrated addition-subtraction and demultiplexing. The all-optical realizations are based on semiconductor optical amplifier (SOA) and Mach–Zehnder interferometer (MZI), which represent one...
متن کاملUltra-Fast All-Optical Half Subtractor Based on Photonic Crystal Ring Resonators
Abstract: In this paper, we aim to design and propose a novel structure for all-opticalhalf subtractor based on the photonic crystal. The structure includes two optical switches,one power splitter, and one power combiner. The optical switches are made of theresonant rings which use the nonlinear rods for dropping operation. The footprint of thedesigned structure is about...
متن کاملImplementation of half adder and half subtractor with a simple and universal DNA-based platform
As a powerful material, DNA presents great advantages in the fabrication of molecular devices and higher-order logic circuits. Herein, by making use of the hybridization and displacement of DNA strands, as well as the formation and dissociation of a G-quadruplex, a simple and universal DNA-based platform is developed to implement half-adder and half-subtractor arithmetic processes. The novel fe...
