The PC-ID computer program has been used to analyze the deviation of the dark current-voltage characteristics of p-n junction silicon solar cells from the ideal two-diode model behavior of the cell, namely the appearance of \"humps\" in the I-V characteristics. The effects of the surface recombination velocity, the minority carrier lifetimes in the base- and emitter regions of the solar cell, as well as the temperature dependence of the I-V characteristics have been modeled using PC-ID. It is shown that the humps in the I-V characteristics arise as a result of recombination within the space-charge region of the solar cell, and occur when conditions for recombination are different from the simple assumptions of the Shockley-Read-Hall theory.","PeriodicalId":156747,"journal":{"name":"Proceedings of the Tenth International Conference on Microelectronics (Cat.

The technique consists mainly of two steps. The first step is to optimize the lengths and widths of microstrip stubs at the emitter and base of the transistor to get maximum reflection coefficient at the output of the non-oscillating circuit comprising the transistor and the microstrip stubs. This is performed using C/NL2 computer program. The second step is to design the output matching circuit to transfer maximum output power at the output load. The design of the matching circuit is performed accurately with analytical design approach using HHSS1 computer program. The final schematic diagram of the designed oscillator with the lengths and widths of microstrip lines is presented.","PeriodicalId":156747,"journal":{"name":"Proceedings of the Tenth International Conference on Microelectronics (Cat.

In this paper, we propose a speaker-independent isolated Arabic word recognition system, based on neural network. The speech signal is usually segmented into a sequence of frames in most of the speech processing techniques. These frames may overlap one another with a specific spacing. At each frame the extracted features form a feature vector. Then, an utterance can be represented by a sequence of feature vectors. This feature vector sequence is considered as speech pattern. The speech recognition is to classify the speech pattern and to identify the spoken words corresponding to the speech patterns. In the present study we use the Kohonen Clustering Networks algorithm to classify the speech pattern.","PeriodicalId":156747,"journal":{"name":"Proceedings of the Tenth International Conference on Microelectronics (Cat.

The modified algorithm needs, at most, half the number of iterations to achieve the same accuracy as the classical algorithm. The modifications are applicable to circular CORDIC in rotation modes. The hardware integration is carried out using field programmable gate arrays (F.P.G.As). To demonstrate the performances of the design, pipeline architecture of the CORDIC algorithm is studied.
