  2. 6. Microwave characterisation of electrodes and field effect transistors based on graphene

    Author : MICHAEL ANDERSSON; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene; graphene electrodes; microwave amplifiers; noise measurements; microwave FETs; CVD graphene; noise modelling; FBARs.; nanofabrication; subharmonic resistive mixers; small-signal FET modelling;

    Abstract : The isolation of the two-dimensional material graphene, a single hexagonal sheet of carbon atoms, is believed to trigger a revolution in electronics. Theory predicts unprecedented carrier velocities in ideal graphene, from which ultrahigh speed graphene field effect transistors (GFETs) are envisioned. READ MORE

  4. 7. Analysis and Design of DLL-Based Frequency Synthesizers for Ultra-Wideband Communication

    Author : Amin Ojani; Atila Alvandpour; Behzad Mesgarzadeh; Per Larsson-Edefors; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Ever increasing demand for high speed transmission of large data between the electronic devices within a wireless personal area network has been motivating the development of the appropriate wireless standards. Ultra-wideband (UWB) communication employs the unlicensed frequency spectrum of 3.1 ‒ 10. READ MORE

  5. 8. Microwave CMOS Beamforming Transmitters

    Author : Johan Wernehag; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Beamforming transmitter; CMOS; frequency doubling power amplifier; polyphase filter; phase shifting;

    Abstract : The increase of the consumer electronics market the last couple of decades has been one of the main drivers of IC process technology development. The majority of the ICs are used in digital applications, and for these CMOS is the choice of technology. The urge to squeeze more transistors on to a given area has led to shrinking feature sizes.
