Abstract
Accurate analytical models of the output voltage andthe power efficiency of voltage doublers and PMOS charge pumpsare derived using dynamic charge transfer waveforms and chargebalance methods, respectively. Since the on-resistance of switchingdevices and the parasitic capacitance can be estimated precisely,the proposed models are more accurate than the other existingmodels. The model-generated values agree well with simulationsand measurements for these two charge pumps using 0.18 μmCMOS technology. The expressions for the ou ....etc

ROBUST DWT-SVD DOMAIN IMAGE WATERMARKING: EMBEDDING DATA IN ALL FREQUENCIES
Watermarking (data hiding) is the process of embedding data into a multimedia element such as image, audio or video. This embedded data can later be extracted from, or detected in, the multimedia for security purposes. A watermarking algorithm consists of the watermark structure, an embedding algorithm, and an extraction, or detection, algorithm. Watermarks can be embedded in the pixel domain or a transform domain. In multimedia applications, embedded watermarks shou ....etc

DETECTING POWER GRID SYNCHRONIZATION FAILURE ON SENSING OUT OF RANGE FREQUENCY OR VOLTAGE


This paper presents the development of a microcontroller based islanding detection for grid connected inverter with very simple under/over voltage and under/over frequency islanding detection algorithms. The system is based on a microcontroller from Atmel 8051 family. The microcontroller monitors the under/over voltage and under/over frequency from utility grid and the processed value of voltage a ....etc

Abstract
The need of low-loss substrate materials with stable dielectric performances over a wide frequency range is a strong
requirement when working at millimeter frequencies, where standard dielectric substrates exhibit prohibitive losses. In
this contribution, the authors focus their attention on a polymer material, the benzocyclobutene (BCB), having a low
dielectric constant equal to 2.65, and a low loss tangent, equal to 0.0008 at 1 GHz, with a stable dielectric behavior
over a broad frequency range, up to THz. The use of BCB ....etc

HIGH THROUGHPUT AND LOW POWER REED SOLOMEN DECODER FOR ULTRA WIDE BAND FREQUENCIES

Abstract:- Reed Solomon (RS) codes have been widely used in a variety of communication systems such as space communication link, digital subscriber loops and wireless systems, as well as in networking Communications and magnetic and data storage systems. Continual demand for ever-higher data rates and storage capacity makes it necessary to devise very high-speed implementations of RS Decoders. Newer and faster implementations of the decoder are being developed ....etc
