New structures of 2n ± 1 modular adders for FPGAs

Two new structures of residue number system (RNS) adders for moduli 2n –1, 2n +1 are presented in this paper. The main idea is the utilization of the prefix computation technique in order to make the correction stage enclosed in the addition process instead of leaving...

Carrier bulk-lifetime measurement during solar cell production

The main material parameter of silicon is the minority carrier bulk lifetime and influences the effectiveness of photovoltaic cells. It may change in the technological process especially during high temperature operations. Monitoring of the carrier bulk-lifetime is necessary for modifying the...

Microscale comparison of solar cell recombination centers

The aim of this work is an experimental microscale comparison of several imperfection types of silicon solar cells which emit visible light under reverse bias condition. The setup with scanning probe microscope (SPM) and sensitive detector is used for the measurement of light emiss...

Design and modeling of the ENR polymer microring resonators add/drop filter for wavelength division multiplexing

We report about design, modeling, fabrication and properties of the polymer optical microring resonator. First step was to design single mode optical polymer ridge waveguides by using BeamPROPTM software and then optical polymer microring resonator was designed by using FullWAVETM software. ...

W-development model extension for embedded system design

At present time, when complexity of the developed devices rises, the developing models became very important [1], [4]. Following of the defined steps, especially during continuously testing, increase reliability of the developed device and then decrease quality cost. It's mainly due to&#...

Temperature dependence of leakage current and noise in Nb2O5 films

Dependence of leakage current on applied voltage was studied for samples of Nb2O5 thin films in the wide temperature range from 10 K to 400 K. Simultaneously low frequency noise characteristics and CV characteristics were measured and evaluated. The studied samples were niobium NbO...

Time-domain pre-distortion technique using raised cosine shaping for high-speed serial signaling

In this paper the innovative time-domain pre-distortion method is proposed. This method (PWM-RC) uses raised-cosine (RC) pulse shaping and pulse-width modulation (PWM) scheme to achieve better output channel data response. The conventional pre-distortion methods based on finite impulse response (FIR)&...

Digital signal soft-processor for audio and video processing

The paper presents a digital signal soft-processor DVSP that was designed using architecture description language ISAC by a tool for processor design called Lissom. First, a basic version of the processor with simple RISC instruction set was designed. Then, based on the target audi...
