  1. 1. An optimization-based approach to efficient design of analog circuits

    Författare :Robert Hägglund; Georges G.E. Gielen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Analog circuit design; computer-aided design; Electrical engineering; Elektroteknik;

    Sammanfattning : Traditional design methods for analog circuits are based on rules-of-thumbs, experience, and trial-and-error approaches involving the use of circuit simulators. It is an unstructured process, which is time-consuming, error prone, and requires the attention of a skilled analog designer. LÄS MER

  3. 2. Studies on design automation of analog circuits : performance metrics

    Författare :Robert Hägglund; Sven Mattisson; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The trend of today is to integrate large systems containing analog and digital circuits on a single chip. This has the advantages of decreased power consumption and cost. In order to reduce the design time for these systems, efficient design automation tools are required. LÄS MER

  4. 3. Characterization of Amino Acid Transporters in the Brain : Molecular and Functional Studies of Members within the Solute Carrier Families SLC38 and SLC6

    Författare :Maria Hägglund; Robert Fredriksson; Farrukh Chaudhry; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Amino acid transporter; Solute Carrier; Glutamine; Leucine; SNAT; B0AT; Neuroscience; Neurovetenskap;

    Sammanfattning : Solute carriers (SLCs) comprise the largest group of transporters in humans and there are currently 52 SLC families. They are embedded in cellular membranes and transport numerous molecules; defects in many of the genes encoding SLCs have been connected to pathological conditions, and several SLCs are potential drug targets.

  5. 4. Värdepedagogik i skolans vardag : Interaktivt regelarbete mellan lärare och elever

    Författare :Robert Thornberg; Gunnel Colnerud; Solveig Hägglund; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; values education; moral education; school rules; discipline; rule practice; moral practice; värdepedagogik; skolregler; fostran; värdegrund; regelarbete; moralisk praktik; normer; socialisation; Education; Pedagogik;

    Sammanfattning : The aim of this study is to explore values education as it takes place in everyday interactions between teachers and students. Focus has been on rule practice between teachers and students, which has been interpreted during the research process as the most salient phenomenon in the practice of values education. LÄS MER

  7. 5. On High-Speed Digital-to-Analog Converters and Semi-Digital FIR Filters

    Författare :Mohammad Reza Sadeghifar; J Jacob Wikner; Robert Hägglund; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DAC; RFDAC; SDFIR; FIR; semi-digital FIR filter; digital-to-analog converter; D A converter; data converter; mixed-signal integrated circuits; mixer DAC; IQ modulator; transmitter;

    Sammanfattning : High-speed and high-resolution digital-to-analog converters (DACs) are vital components in all telecommunication systems. Radio-frequency digital-to-analog converter (RFDAC) provides high-speed and high-resolution conversion from digital domain to an analog signal. RFDACs can be employed in direct-conversion radio transmitter architectures. LÄS MER
