1. ABSTRACT: Data transmission through power lines has received increasing attention in recent years. In fact the electrical energy distribution system is a big back bone that can be use for data communication. The interest for this medium includes automatic reading of energy meter, management of electrical distribution system, automation of buildings, and high speed data rate connection within...

This paper presents a fast and low-power Static Random Access Memory (SRAM) design. SRAM are widely used in computer systems and many portable devices. Proposed SRAM is faster because of precharging at a desired voltage. For the most recent CMOS technologies leakage power dissipation has become a major concern. According to the International Technology Roadmap for Semiconductors (ITRS), leakage...

Blumlein pulsers are well suited devices for high voltage pulse generation in the range of nanoseconds or microseconds. They consist of pieces of transmission lines charged in parallel and discharged synchronously in series into the load by using a single switch. The main problems with this type of circuit are the presence of the shield cable impedance that contributes to the power loss of the ...

Due to low-power and reliability requirements, supply voltage is constantly decreasing. On the other hand, high speed operation is required along with increasing memory size. In a CMOS SRAM, power can be saved and cycle time reduced if bit lines are not precharged to VDD. The aim of this work is to analytically derive a model for the design of precharge and self-timing, maintaining the core-cel...

Many epidemiologic studies suggest a relationship between incidence of diseases like cancer and leukemia and exposure to 50/60 Hz magnetic fields. Some studies suggest a relationship between leukemia incidence in populations residing near high-voltage lines and the distance to these lines. Other epidemiologic studies suggest a relationship between leukemia incidence and exposure to 50/60 Hz mag...

Power cable is widely used in Extra High Voltage (EHV), High Voltage (HV) transmission, Medium Voltage (MV) sub-transmission, and MV / Low Voltage (LV) distribution applications. Basically, the protection principles used for cable are similar with the ones for overhead transmission line. However, the inherent characteristics of cables make its fault behavior more complicate than that of transmi...

In this paper, we investigate the energy problem of monitoring sensors on high-voltage power transmission lines and propose a wireless charging scheme for a Radio Frequency IDentification (RFID) sensor tag to solve a commercial efficiency problem: the maintenance-caused power outage. Considering the environmental influences on power transmission lines, a self-powered wireless energy relay is de...
