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

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

    Abstract : 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. READ MORE

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

    Author : Robert Hägglund; Sven Mattisson; Linköpings universitet; []

    Abstract : 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. READ MORE

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

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

    Abstract : 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.

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

    Author : Mohammad Reza Sadeghifar; J Jacob Wikner; Robert Hägglund; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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;

    Abstract : 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. READ MORE
