  1. 1. Microwave CMOS Beamforming Transmitters

    University dissertation from Tryckeriet i E-huset, Lunds universitet

    Author : Johan Wernehag; [2008]
    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.

  2. 2. Micro- and Millimeter Wave CMOS Beamforming Receivers

    University dissertation from Tryckeriet i E-huset, Lunds universitet

    Author : Andreas Axholt; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; beamforming; CMOS; front-end; microwave; millimeter wave; phase-locked loop; phased-array;

    Abstract : The available bandwidth in wireless communication systems, such as the 802.11 family, is very limited. Together with the ever increasing data traffic, this causes problems. New possibilities are, however, available thanks to wide license-free bandwidth allocated at higher frequencies. READ MORE

  3. 3. Low Voltage CMOS Radio Receiver Front-End Design

    University dissertation from Department of Electroscience, Lund University

    Author : Fred Tillman; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; Electrical engineering; Elektronik; Electronics; Elektronik och elektroteknik; Electronics and Electrical technology; Polyphase Filter; Quadrature Signals; Nonlinearity; Distortion; Passive Mixer; Mixer; Low Noise Amplifier; CMOS; Front-End; Low Voltage; Radio; Receiver;

    Abstract : The mass production of integrated circuits for digital electronics has made CMOS technology the most frequently used IC process today. Thanks to the large production volume, CMOS has increasingly become the most cost efficient technology of choice, and the fast development of small, high speed CMOS devices has made the technology feasible for many RF applications.

  4. 4. Integrated Variable-Gain and CMOS Millimeter-Wave Amplifiers

    University dissertation from Department of Electroscience, Lund University

    Author : Mohammad Anowar Masud; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LNA; MMIC; FinFET; CMOS; HEMT; GaAs; WLP; VGA; BCB;

    Abstract : Variable Gain Amplifier finds extensive use in the high frequency demonstrators specially those operating in the millimeter-wave regions and beyond where the incoming RF signal level can have wide variations. To maintain a constant signal level an IF VGA has been designed that can offer a dynamic variation of gain as much as 45 dB together with a high maximum gain and a low noise figure. READ MORE

  5. 5. Low Power Techniques for Fast CMOS Buffer Memories

    University dissertation from Department of Information Technology, Lund Univeristy

    Author : Jonas Alowersson; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Systems engineering; low-power; throughput; buffer memory; CMOS; SRAM; computer technology; Data- och systemvetenskap;

    Abstract : The thesis deals with circuit-level aspects of CMOS buffer SRAMs where the data throughput rate is a more important metric than access time or storage capacity. One aspect is the increased write cycle related power consumption that is the consequence of a high write ratio combined with a long word-length. READ MORE
