in this paper, a new structure possessing the advantages of low-power consumption, less hardware and high-speed is proposed for fuzzy controller. the maximum output delay for general fuzzy logic controllers (flc) is about 86 ns corresponding to 11.63 mflips (fuzzy logic inference per second) while this amount of the delay in the designed fuzzy controller becomes 52ns that corresponds to 19.23 m...

Because of an improvement of wireless communication technologies, cables are taken away step by step from an electrical equipment. Now, a power cable is the last wire connected to the equipment. Therefore, wireless power transfer (WPT) technology is desired. Conventionally, microwave power transfer and magnetic induction have been used for this purpose. Microwave power transfer technology utili...

Energy efficiency in large data centers is already a concern for many businesses because of the high density of energy consumption. Rising energy costs and global environmental concerns have prompted Information Technology (IT) professionals to also take a closer look at client personal computer (PC) energy consumption. Intel researchers interviewed IT professionals about the monitoring and con...

Technology for power systems of modern computer/telecom equipment is facing extremely tough challenges due to continuously increasing power-density and efficiency requirements. Meeting these requirements will require significant technology advancements in system architectures, devices and materials, topology optimization, and packaging/thermal design. In this paper, major technology challenges ...

Power MOSFETs based on superjunction technology have become the industry norm in high-voltage switching converters. They offer lower RDS(on) simultaneously with reduced gate and output charges, which allows for more efficient switching at any given frequency. Prior to the availability of superjunction MOSFETs the dominant design platform for high-voltage devices was based on planar technology. ...

full adder cell is often placed in the critical path of other circuits. therefore it plays an important role in determining the entire performance of digital system. moreover, portable electronic systems rely on battery and low-power design is another concern. in conclusion it is a vital task to design high-performance and low-power full adder cells. since delay opposes against power consumptio...

In recent years, due to the fact that non-renewable energies come to an end, renewable energy is expected to provide a significant part of the future needs of Iran. Among these energies, solar energy is a suitable option for a wide range of the country, due to availability, proper radiation intensity, and high sunshine times during the year (about 300 sunny days per year). The purpose of this p...

This thesis studied the application of strained-Si technology to RF power LDMOSFETs. Key issues for its implementation were determined to be thermal budget restrictions, gate oxide formation and impact ionization effects. 2D simulations were carried out to explore the design space of the strained-Si LDMOSFET. In order to address the thermal budget restrictions, use of a high-tilt implant for th...
