    • Bærebølgegjenvinning i radio-link 

      Dale, Anders (Master thesis, 2009)
      Denne masteroppgaven tar for seg et problem fremsatt av Kongsberg Defence & Aerospace. KDA ønsker i en digital radiolinje-link å operere ved 10 dB signal-støyforhold på inngangen til mottakeren. Dette skaper problemer for ...

    • Characterization of medical piezoelectric ultrasound transducers using pulse echo methods. 

      Mylvaganam, Janani (Master thesis, 2007)
      In this thesis, a measurement set-up has been developed to characterize high frequency medical ultrasound transducers using a pulse echo set-up. This work is a continuation of an earlier project. The aim of this project ...

    • CMOS Class D Audio Amplifier Implementations for Microcontroller Circuits 

      Braathen, Åsmund (Master thesis, 2007)
      A class D amplifier implementation on an AVR 8-bits microcontroller is presented in this thesis. The solution uses a pulse modulation scheme known as uniform sampled pulse width modulation (UPWM). Eight times interpolation ...

    • Compact Modeling of the Current through Nanoscale Double-Gate MOSFETs. 

      Holen, Åsmund (Master thesis, 2009)
      In this thesis a compact drain current model for nanoscale double-gate MOSFETs is presented. The model covers all operation regimes and bias voltages up to 0.4V. The modeling is done using conformal mapping techniques ...

    • Comparator-Based Switched-Capacitor Integrator for use in Delta-Sigma Modulator 

      Torgersen, Svend Bjarne (Master thesis, 2009)
      A comparator-based switched capacitor integrator for use in a Delta Sigma ADC has been designed. Basic theory about comparator-based circuits has been presented and design equations have been developed. The integrator had ...

    • Compensation of Loudspeaker Nonlinearities: - DSP implementation 

      Øyen, Karsten (Master thesis, 2007)
      Compensation of loudspeaker nonlinearities is investigated. A compensation system, based a loudspeaker model (a computer simulation of the real loudspeaker), is first simulated in matlab and later implemented on DSP for ...
