Development of a MAT LAB based Silicon Process Technology Simulator.

 

 

Abstract

 

It is proposed to develop an advanced simulator for various steps involved in silicon process technology, incorporating some of the latest models and findings not available in the currently available simulators. The simulator will utilize the vast computational potential of MAT LAB. It is intended to be an advanced low cost simulator within easy reach of academicians and small industries.

 

The area of Silicon Integrated Circuit (IC) processing has assumed great importance specially with the wide spread use of Application Specific IC (ASIC) technology. IC process simulator is an essential tool for process design. The currently available tools are all stand-alone and hence are very complicated and exorbitantly expensive. The powerful computational softwares like MA TLAB are quite common and available in almost every computational environment. The use of vast potential of MA TLAB will result in more advanced and low cost process simulator.

A Novel Compact Microwave Filter.

 

 

Abstract

 

Filters are very important component for microwave transmitters and receivers. They usually placed before amplifiers, balanced mixers and antenna feeds. Recent years have seen a worldwide effort to develop small size filters due to the trends of compact mobile phones. Applications in present-day mobile communication system usually require small size RF devices in order to meet the miniaturization requirements of mobile units. This research proposes analysis, design, simulation (using software-packages) and implementation of a small size RF /microwave filter for modem communication units by using the technology and techniques already possible in the microwave laboratory in the department of electrical engineering at KSU. The performance of the small size filter will be measured by the Vector Network analyzer that is used typically for microwave measurements.

 

The research objective is to design and implement a microwave microstrip bandstop filter that has a small size, light weight and good performance. This microwave filter will be a good candidate for modem sensitive communication applications.

A Dual-Band Microwave Power Divider Using T-Sections.

 

 

Abstract

 

The power dividers and combiners are very important component for microwave power amplifiers, balanced mixers and antenna feeds. Recent years have seen a worldwide effort to develop dual-band power dividers due to the trends of multiband mobile phones. The Wilkinson power divider that only operates at one design frequency and at all of its odd harmonics is not suitable for some dual band operations, e.g., for downlink operation both at the Global system of Mobile Communication band (GSM) and at the Personal communication system band (PCS). Applications in present-day mobile communication system usually require smaller size RF devices in order to meet the miniaturization requirements of mobile units. This research proposed analysis, design, simulation (using software-packages) and implementation of a dual-band power divider for modem communication units by using the technology and techniques already possible in the microwave laboratory in the department of electrical engineering at KSU. The performance of the dual-band power divider is measured by the Vector Network analyzer that is used typically for microwave measurements.

 

Wide Band Clock Recovery Circuit.

 

 

Abstract

 

One of the most important problems that electronic circuits and modem communication systems in data transfer is noise and jitter in particular. And these problems are due to internal parts of these circuits and systems, weather changes, and external effects. In this project, the problem of jitter in data transfer will be studied, analyzed from different perspectives, and some solutions will be suggested. The goal of this project is to build an experimental model using the personal computer and laboratory circuits to decrease jitter and noise in electronic systems and circuits.

 

A Triple-Band Power Divider Based on Metamaterial Lines.

 

 

Abstract

 

This research is focused on the Metamaterials which are formed by loading transmission lines periodically with series electronic components. The syntheses of metamaterial lines require a host transmission line medium such as microstrip or coplanar waveguide.

 

Components are then inserted periodically by either soldering chip lumped components or printing them on the substrate. Metamaterial lines support a fundamental backward-wave mode, thereby demonstrating an index of refraction that is negative. Therefore, such structures when arranged in two dimensional grids produce negative refraction and focusing. Similar structures developed by other groups internationally have demonstrated superior characteristics such as compactness, operational flexibility, and wider bandwidth over conventional devices.

 

 

Automatic Eye Localization from a Face Image.

 

The eyes can be considered salient and relatively stable features on the face in comparison with other facial features. Therefore, when we detect facial features, it is advantageous to detect eyes before the detection of other facial features. The positions of other facial features can be estimated using the eye positions. Eye detection plays an important role in applications such as video conferencing and vision assisted user interfaces.

 

The principle of this project is to detect the both of eyes from a face image. The task is divided into two main objectives as follows: (1) To localize the face region from a face image (2) To design an algorithm to detect the both of eyes from the face region.

In this research, design of efficient and high performance architecture of matrix multiplier is proposed. Matrix multiplier is the fundamental operation in many industrial and commercial applications. The designed architecture implemented in FPGA hardware will result in significant speedup of the algorithm where it is employed.

 

Algorithms used in digital signal, image and video processing, numerical analysis, computer graphics and vision, robotics involve matrix multiplication. Matrix multiplier is a basic building block in such applications. The use of efficient and high performance matrix multiplier will thus result in optimized realization of algorithms used in high performance computing applications.

 

Novel Correlated Coding Technique for Fiber Fault-Surveillance in Existing and Next-Generation Fiber-to-the-Home Networks.

 

Fibre-to-the-home (FTTH) is the evolving solution for the last/first mile telecom bottleneck. Extensive FTTH deployments have been carried out in North America and Japan over recent years [1]. The demand for FTTH services is growing at 80% per year compared to 3% for DSL in Japan. The number of customers sharing the same fibre currently ranges from 16 to 32, and near term industry forecast predict ranges from 64 to 128.

 

Industrial and academic laboratories already report 1024 customers sharing the same fibre by means of time division multiplexing together with wavelength division multiplexing of passive optical networks (TDM/WDM-PON). The need remains for centralized monitoring of these complex optical network infrastructures, and many technologic challenges remain. Indeed, no known product, nor technology, offers a serious solution for high capacity PONs supporting more than 20 to 30 customers per fibre [2-6].

 

We expect this new proposal will extend the capacity of previous monitoring system 4 to 8 times, hence allowing the monitoring of 128 to 256 customers in an FTTH network. Our new technique exploits a new coding/decoding concept that combines our previous coding proposals with correlation technique that is popular in standard optical-time-domain-reflectrometry (OTDR). This involves more advanced processing of the monitoring signal at the network central office (CO).
