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...

Skyrmion-based devices are promising candidates for non-volatile memory and low-delay time computation. Many skyrmion-based execute operation by controlling skyrmion trajectory, which can be impeded the Hall effect. Here, design of arithmetic built on synthetic antiferromagnetic (SyAF) structures is presented, where structure greatly suppress In this study, operations half adder, full XOR logic...

Based on the characteristics of magnetic beads and DNA, a simple and universal platform was developed for the integration of multiple logic gates to achieve resettable half adder and half subtractor functions. The signal reporter was composed of a split G-quadruplex DNAzyme and AuNP-surface immobilized molecular beacon molecule. The novel feature of the designed system is that the inputs (split...

Progress in high-speed GaAs charge-coupled device (CCD) research is described. Experimental and modelling results are reported for two different structures; capacitive gate CCD's and resistive gate CCD's. A charge packet replicator/subtractor circuit is discussed.

This paper presents on-chip implementation of high speed low latency floating point adder /subtractor with high accuracy performance for FFT in OFDM transceiver. However due to high performance and high resolution, the floating point adder is matched with power network applications as well. The design was implemented for 32-bit pipelined adder/subtractor which satisfied IEEE-754 Standard for fl...

The biological deoxyribonucleic acid (DNA) strand has been increasingly seen as a promising computing unit. A new algorithm is formulated in this paper to design any DNA Boolean operator with molecular beacons (MBs) as its input. Boolean operators realized using the proposed design methodology is presented. The developed operators adopt a uniform representation for logical 0 and 1 for any Boole...

Feedback control is widely used in chemical engineering to improve the performance and robustness of chemical processes. Feedback controllers require a 'subtractor' that is able to compute the error between the process output and the reference signal. In the case of embedded biomolecular control circuits, subtractors designed using standard chemical reaction network theory can only realise one-...

This paper proposes D4 FLMS-GSC algorithm interpreted as Daubechies D4 wavelet filter instead of subtractor filter which processes array antenna output. The structure of the proposed D4 FLMS-GSC algorithm has characteristic of reducing the computational requirement one-half compared to the FLMS-GSC algorithm. In addition, we obtain the MSE characteristics and adaptive beampattern of the D4 FLMS...

-In this paper a 4 bit parallel adder/subtractor circuit has been designed and analyzed. The circuit uses a controlled adder/subtractor circuit which converts the negative numbers into their 2’s complement. A comparative study of the silicon area and the power consumption has been done in the circuit using different channel lengths such as 65nm, 45nm. The circuit is designed and simulated using...
