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

    University dissertation from Department of Information Technology, Lund Univeristy

    Author : Jonas Alowersson; Lunds universitet.; Lund University.; [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

  4. 4. All Digital Polar Transmitter Design for Software Defined Radio Architecture and Low Power Circuit Implementation

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Liang Rong; KTH.; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Switching Power Amplifier; All Digital Polar Transmitter; Lowpass Sigma Delta Modulation; Software Defined Radio; RFID; H-Bridge Architecture; Resonating; Filter Matching Network.; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : The evolving wireless communication technology is aiming highdata rate, high mobility, long distance and at the meantime, co-existwith various different standards. This developing trend requires ahighly linear transceiver system and it causes the problem of lowefficiency due to the large crest factor of signals. READ MORE

  5. 5. Improving Low-Power Wireless Protocols with Timing-Accurate Simulation

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Fredrik Österlind; Uppsala universitet.; Uppsala universitet.; SICS.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication; Low-Power Wireless Protocols; Wireless Sensor Networks; Contiki; Cooja; Simulation;

    Abstract : Low-power wireless technology enables numerous applications in areas from environmental monitoring and smart cities, to healthcare and recycling. But resource-constraints and the distributed nature of applications make low-power wireless networks difficult to develop and understand, resulting in increased development time, poor performance, software bugs, or even network failures.
