A new approach for designing an ultra wideband (UWB) CMOS low noise amplifier (LNA) is presented. The aim of this design is to achieve a low noise figure, reasonable power gain and low power consumption in 3.1-10.6 GHz. Also, the figure of merit (FOM) is significantly improved at 180nm technology compared to the other state-of-the-art designs. Improved π-network and T-network are used to obt...

Ultra-wideband (UWB) communication (Win & Scholtz, 1998; Yang & Giannakis, 2004a) is a fast emerging technology since the Federal Communication Commission released a spectral mask in the spring of 2002. The major reason for UWB technology to receive much attention is its promising ability to provide low-power consumption, high bit rate and multipath resolution, and coexist with the narrow-band ...

With rapid development of multi-core processor, the communication becomes a bottleneck increasingly. Traditional electronic connections face a serious complexity restriction. The network on chip has been a prevalent solution in the present. However using the recent technology (ultra-wide band interconnection) technology, the over-all performance including delay and throughput can achieve a new ...

Due to the low power spectral properties of ultra wideband (UWB) signals, the technology is suitable to be used, e.g., in covert military applications. The open literature lacks of UWB radio channel models that are generated for outdoor use. This paper describes the radio channel measurement campaign carried out to increase the knowledge of the UWB propagation mechanisms in typical Finnish fore...

Recently, an ultra wideband (UWB) impulse radio draws much attention due to its potential low cost and low power consumption properties. The Federal Communications Commission (FCC) is currently working on setting emission limits that would allow UWB communication systems to be deployed on an unlicensed band following the Part 15 rules for radiated emissions of intentional radiators [1]. The UWB...

Ultra Wide Band (UWB) impulse radio is a promising technology for future short-range, low-power, low cost and high data rate ad hoc networks. The technology is being explored in a number of research projects. While most UWB research for this class of networks is concentrating on the physical layer, little research has been published on link layer protocols which exploit the specifics of UWB imp...

Currently, there is an increased interest in ultra-wideband (UWB) technology for use in sev‐ eral present and future applications. UWB technology received a major boost especially in 2002 since the US Federal Communication Commission (FCC) permitted the authorization of using the unlicensed frequency band starting from 3.1 to 10.6 GHz for commercial com‐ munication applications [1]. Although ex...

Ultra Wideband (UWB) is a radio technology that can be used at very low energy levels for short-range high-bandwidth communications by using a large portion of the radio spectrum. Ultra Wideband (UWB) systems transmit signals across a much wider frequency than conventional systems and are usually very difficult to detect. The focus of this research is to model the Ultra wideband (UWB) channel f...

The next generation RFID system for ubiquitous identification and sensing requires both energy and system efficiency. This paper describes an efficient passive RFID system using impulse ultra-wideband radio (IR-UWB), at a 10m operation range. Unlike conventional passive RFID systems which rely on backscatter and narrowband radio, IR-UWB is introduced as the uplink (communication from a tag to a...

Electronic devices steadily penetrate almost every area of life and transform our surrounding more and more into a dense heterogeneous wireless network. To enable the potential of such a network, a wireless technology with high scalability potential is required supporting devices with ultra low power consumption as well as high data rates. Ultra wideband (UWB) is a promising technology inherent...
