AbstractIn today’s world everyday a new technology which is faster, smaller and more complex than its predecessor is being developed. The increased number of transistors packed onto a chip of a conventional system results in increased power consumption that is why Reversible logic has drawn attention of Researchers due to its less heat dissipating characteristics. Reversible logic can be impose...

By increasing the demand of enhancing the ability of processors to handle the more complex and challenging processors has resulted in the integration of a number of processor cores into one chip. Still the load of on the processor is not less in generic system. An Arithmetic Logic Unit (ALU) is the heart of all microprocessors. It is a combinational logic unit that performs its logical or arith...

This paper presents an accurate theoretical model for the study of concatenation of optical multiplexers/demultiplexers (MUXs/DMUXs) in transparent multiwavelength optical networks. The model is based on a semianalytical technique for the evaluation of the error probability of the network topology. The error-probability evaluation takes into account arbitrary pulse shapes, arbitrary optical MUX...

Reconfigurable optical add/drop multiplexers (ROADMs) can be classified into three categories based on their underlying switching technologies. Category I consists of a single large optical switch; category II is composed of a number of small optical switches aligned in parallel; and category III has a single optical switch and only one wavelength being added/dropped. In this paper, to evaluate...

This paper describes a novel logic decomposition theory and a practical logic synthesis system, BDS. It is based on a new binary decision diagrams (BDD) decomposition technique which supports all types of decomposition structures, including AND, OR, XOR, and complex MUX, both algebraic and Boolean. As a result, the method is very efficient in synthesizing both AND/OR and XOR-intensive functions...

In this paper, an irradiance-based absolute radiometric calibration campaign at Baotou site during June and July 2018 was described. This made use of six tarps. The synchronous measurements parameters such as surface reflectance, atmospheric parameters, diffuse-to-global irradiance ratio were collected the satellite overpass. top-of-atmospheric radiance predicted by radiative transfer model wit...

The idea of using radiation in the 0.1–1.0 THz range as carrier waves for free-space wireless communications has attracted growing interest in recent years, due to the promise of the large available bandwidth1,2. Recent research has focused on system demonstrations3,4, as well as the exploration of new components for modulation5, beam steering6 and polarization control7. However, the multiplexi...

This work presents an interpolated flying-adder(FA-) based frequency synthesizer. The architecture of an interpolated FA, which uses an interpolated multiplexer (MUX) to replace the multiplexer in conventional flying adder, improves the cycle-to-cycle jitter and root-mean-square (RMS) jitter performance. A multiphase all-digital phase-locked loop (ADPLL) provides steady reference signals for th...

At-speed scan testing has become necessary to detect the growing population of timing defects in today’s nanometer-scale process. There are several at-speed delay test methods available in the industry to generate the delay patterns. Manufactures are continuing to look for ways to improve the effectiveness of at-speed delay test. The key is to create high quality, cost effective tests for these...
