    • Automated Self-Test of an Analog Delta-Sigma Modulator 

      Pedersen, Trond Jarle (Master thesis, 2007)
      This project investigates the feasibility of automating the test of ΔΣ-modulators using circuitcomponents available on 8-bit microcontrollers, and by doing so reducing test costs.A Built-In-Self-Test (BIST) scheme, using ...

    • 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 ...

    • Design of a low-cost CC-VFC for one-celled Li-Ion batteries 

      Hafslund, Fredrik (Master thesis, 2007)
      The Lithium-ion battery is today used by close to every portable battery powered device, and this marked is constantly increasing because not only are the products the consumer have had for years getting more and more ...

    • Digital-to-Analog Conversion in High Resolution Audio 

      Løkken, Ivar (Doctoral Theses at NTNU, 1503-8181, Doctoral thesis, 2008)
        This thesis describes theoretical and simulation-based work on digital-to-analog conversion for high resolution audio. The emphasis of the work has been exploration and clarification of issues of contention in ...

    • Metallization scheme and release methods for fabrication of RF MEMS switches 

      Saha, Shimul Chandra; Sæther, Trond; Jensen, Geir uri; Poppe, Erik; Sagberg, Håkon (Chapter; Peer reviewed, 2007)

    • Modelling, Simulation and Implementation Considerations of High Speed Continuous Time Sigma Delta ADC 

      Kaald, Rune (Master thesis, 2008)
      A found state of the art Continuous Time Sigma Delta ADC is modelled and simulated for the presence of nonidealities. A comparison between two Excess Loop Delay compensation techniques is done, the digital differentiation ...

    • Realisering av high-end delta-sigma DAC i FPGA 

      Olsen, Lasse Haugnes (Master thesis, 2006)
      Oppgaven har gått ut på å lage en high-end delta-sigma DA-konverter for FPGA. Prinsippet for en slik DA-konverter er at det analoge utgangssignalet genereres ved å lavpassfiltrere et 1-bit digitalt utgangssignal fra ...

    • "Retention cells" for lav effekts digital design 

      Eikeland, Ørjan (Master thesis, 2007)
      En studie av ulike retention latch kretstopologier er foretatt og egenskaper til både statiske og dynamiske løsninger er vurdert. Retention egenskapen til en latch beskriver dens mulighet for å settes i et søvnmodus samtidig ...

    • Tunable lowpass filter with RF MEMS capacitance and transmission line 

      Saha, Shimul Chandra; Hanke, Ulrik; Sagberg, Håkon; Fjeldly, Tor A; Sæther, Trond (Journal article; Peer reviewed, 2012)
      We have presented an RF MEMS tuneable lowpass filter. Both distributed transmission lines and RF MEMS capacitances were used to replace the lumped elements. The use of RF MEMS capacitances gives the flexibility of tuning ...
