Diverse advanced logic circuits are fabricated to implement arithmetic functions based on a simple and single molecular beacon platform, including half adder, half subtractor, full adder, full subtractor, and a digital comparator. Dual fluorescence outputs are generated in parallel and a constant threshold value is set to build all the logic circuits. The developed enzyme-free DNA system provid...

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...

A novel synchronous dual-bit adder design, realized using the elements of commercial standard cell libraries is presented in this article. The adder embeds two-bit carry look-ahead generator functionality and is realized using simple and compound gates of the standard cell library. The performance of the proposed dualbit adder design is evaluated and compared vis-à-vis the conventional full add...

Quantum computers require quantum processors. An important part of the processor of any computer is the arithmetic unit, which performs binary addition, subtraction, division and multiplication, however multiplication can be performed using repeated addition, while division can be performed using repeated subtraction. In this paper we present two designs using the reversible R gate to perform t...

In order to design radiation-hardened LSIs for space applications, single event transient (SET) effects on cascade voltage switch logic (CVSL) circuits have been investigated using SPICE. Static CVSL and clocked CVSL (CVSL) circuits have been successfully fabricated utilizing a double polysilicon double metal N-well CMOS technology. A CVSL half adder, a CVSL half adder and a CVSL full adder hav...

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...

Unimolecular half-adders based upon an arylvinyl-bipyridyl fluorophore platform were demonstrated where all the chemical input combinations were fully processed by half-adder molecules to generate the arithmetic results of the entire truth table.
