Design of a 10-bit Segmented Current-Steering CMOS D/A Converter for High Speed Communication System
Abstract: In the present work, design of a 10-bit digital-to-analog (D/A) converter using current segmentation architecture in 0.35 µm double-poly, four-metal, CMOS process has been attempted. The measured differential nonlinearity (DNL) and integral nonlinearity (INL) are 0.8 and 2.5 least significant bits (LSBs) respectively. For sampling frequency of 12-MSample/s, the spurious free dynamic range (SFDR) is better than 56 dB for signal up to Nyquist rate. The worst case power consumption …

Obstruction Organizing Network Based Protocol Using Congestion Free Router
Abstract: AbstractThe web’s wonderful quantifiability and strength lead to half from the end-to-end nature of internet congestion management. End-to-end congestion management algorithms alone, however, are unable to stop the congestion collapse and unfairness created by applications that are unresponsive to network congestion. To address these maladies, I propose and investigate a unique congestion-avoidance mechanism referred to as Congestion Free Router (CFR). CFR entails the exchange of feedback between routers at the …

Effect of Aluminium Mole Fraction on the AlGaN/GaN HEMTs with 10 nm AlGaN Nano-Layer
Abstract: We report the effect of aluminium mole fraction on drain current in AlGaN/GaN high electron mobility transistors (HEMTs). The drain current increases with the drain voltage. Also, the effect of gate voltage on drain current as well as the effect of drain voltage on source current is studied. The drain current is invariant and nearly 0 mA corresponding to the aluminium mole fractions of 0.10, 0.15, 0.20, and 0.25 related …

Texture Segmentation Using Multichannel Filtering And Kohonen’s Self Organizing Map
Abstract: The texture is very important cue in region based segmentation of images. Texture features play a very important role in computer vision and pattern recognition. Texture segmentation can be broken down into two areas, feature extraction and clustering. In this paper, we implement two stage of feature extraction technique using multichannel filter and Self Organizing Map (SOM). Firstly, we go through channel filters, also known as 2-D Gabor functions. The …
