3D IC technology stacks multiple layers of active silicon circuits to reduce interconnect length and delay. Shorter global interconnects in 3D ICs are expected to reduce both switching energy and cycle time compared to conventional 2D designs. 3D fabrication involves bonding or epitaxial growth of multiple processed silicon wafers. EDA tools are needed to automate the placement, routing, and design of circuits across multiple layers to fully leverage 3D integration.

A proposal and simulation analysis for a novel architecture of gate-all-aroun...
A proposal for a novel gate-all-around (GAA) polycrystalline silicon nanowire (poly-SiNW) field effect transistor (FET) is presented and discussed in this paper. The device architecture is based on the realization of poly-SiNW in a V-shaped cavity obtained by tetra methyl ammonium hydroxide (TMAH) etch of monocrystalline silicon (100). The device’s behavior is simulated using Silvaco commercial software, including the density of states (DOS) model described by the double exponential distribution of acceptor trap density within the gap. The electric field, potential, and free electron concentration are analyzed in different nanowire regions to investigate the device's performance. The results show good performance despite the high density of deep states in poly-SiNW. This can be explained by the strong electric field caused by the corner effect in the nanowire, which favors the ionization of the acceptor traps and increases the free electron concentration.
A CPW-fed Rectangular Patch Antenna for WLAN/WiMAX Applications
This paper presents a CPW fed Rectangular
shaped patch antenna for the frequency 3.42GHz which
falls in WiMAX and 5.25GHz for WLAN applications.

-24dB and -18dB for WiMAX and WLAN applications,
antenna efficiency about 90%, gain above 3.5dB are
obtained. The compact aperture area of the antenna is

Artificial intelligence in the design of microstrip antenna
This work presents a Neural Network model for the design of Microstrip Antenna for a desired frequency between 3.5 GHz to 5.5 GHz. The results obtained from the proposed method are compared with the results of IE3D and are found to be in good agreement. The advantage of the proposed method lies with the fact that the various parameters required for the design of specific Microstrip antenna at a particular frequency of interest can be easily extracted without going into the rigorous time consuming, iterative design procedures using a costly software package. In this work, a general design procedure is suggested for the Microstrip antennas using artificial neural networks and this is demonstrated using the rectangular patch geometry.

Digital watermarking with a new algorithm
Abstract Everyday millions of data need to transmit through a distinct channel for various purposes; as a result there is a certain chance of third person interruption on that data. In this regards digital watermarking is one of the best solution. This paper proposes a new embedding algorithm (NEA) of digital watermarking. The algorithm is performed for digital image as data. The performance is compared for NEA and well established Cox's modified embedding algorithm. The watermarking is based on discrete wavelet transforms (DWT) and discrete cosine transforms (DCT). The acceptance of the new algorithm is measured by the two requirements of digital watermarking. One is imperceptibility of the watermarked image, measured by peak signal to noise ratio (PSNR) in dB; another one is robustness of the mark image, measured by correlation of original mark image and recovering mark image. Here a 512×512 gray scale "Lena" and "Cameraman's" image is taken as host images, and a 128×128 gray scale image is taken as mark image for 2 level of DWT. The simulation results for different attacking conditions such as salt and pepper attack, additive white Gaussian noise (AWGN) attack, jpg compression attack, gamma attack, histogram attack, cropping attack, sharpening attack etc. After different attacks the changing tendency PSNR for both algorithms are similar. But the mean square error (MSE) value of NEA is always less than Cox’s modified algorithm, which means that after embedding the changes of the host image property lower for NEA than Cox’s algorithm. From the simulation results it can be said that NEA will be a substitute of modified Cox’s algorithm with better performance. Keywords: Digital watermark, DWT, DCT, Cox’s modified algorithm, Lena image, Cameraman image, AWGN, JPG, salt and pepper attack, PSNR, correlation, MSE.
