  1. 36. Direct RF sampling receivers for wireless systems in CMOS technology

    Författare :Darius Jakonis; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The fast development of wireless communication systems asks for more flexible and more cost-effective radio architectures. A long term goal is a software defined radio, where communication standards are chosen by reconfiguration of hardware. LÄS MER

  3. 37. Low-Noise Amplifier Design for Ultra-Wideband Systems

    Författare :Adriana Serban Craciunescu; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The low-noise amplifier (LNA) remains a critical block in every receiver front-end. As the development of the widcband, low-power and low-cost wireless systems continues, new LNA topologies and design methodologies have become one of the most interesting challenges in the field of radio frequency system design.

  4. 38. Extended Application of Robust Design Methodology

    Författare :Vanajah Siva Subramaniam; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; practices; life cycle approach; Robust design methodology; back-end data; sustainable product development;

    Sammanfattning : Robust Design Methodology (RDM), a subset of Quality Management (QM), is an approach applied to the design phase of product development in order to manage variability in product performance by creating insensitivity to noise factors. Noise factors are sources of variation that cannot be readily controlled. LÄS MER

  5. 39. Modelling, Analysis and Design of RF Mixed-Signal Mixer for Wireless Communications

    Författare :Li Li; KTH; []
    Nyckelord :RF; INTEGRATED CIRCUITS; MIXED-SIGNAL; MIXER; WIRELESS COMMUNICATIONS; NOISE ANALYSIS; SUBSTRATE COUPLING.;

    Sammanfattning : The explosive growth of the market for wirelesscommunications is driving low cost, highly integrated designsand complex RF/analog mixed-signal integrated circuit (RF AMSIC) products. RF transceiver application is one of the mostimportant wireless applications. LÄS MER

  7. 40. New directions in RF LNA design

    Författare :Stefan Andersson; Christian Fager; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The RF field develops fast today and to meet the increasing needs from more and more users and higher and higher data rates for mobile terminals the number of wireless standards are rapidly increasing. This has lead to an increased number of frequency spectra dedicated for wireless communication, such as the recent ones for WCDMA, Bluetooth, and WLAN. LÄS MER
