  1. 11. Eddy Current Sensor for Tissue Conductivity Measurement

    Master-uppsats, Institutionen för fysik

    Författare :Milad Tanha; [2013]
    Nyckelord :Tissue conductivity; eddy current sensor; biomedical instruments;

    Sammanfattning : Electrical conductivity of the tissue can be measured via eddy current sensor and it can be used to distinguish cancerous tissue from healthy tissue. The conductivity of healthy and cancerous tissues is different due to the strong correlation between necrosis in tumor and the associated membrane breakdown [10]. LÄS MER

  3. 12. Design of Variable Attenuators Using Different Kinds of PIN-Diodes

    Master-uppsats, Fysik och elektroteknik; Tekniska högskolan

    Författare :Imran Choudhury; [2013]
    Nyckelord :PIN diode; attenuator; variable attenuator; Imran choudhury;

    Sammanfattning : Variable attenuators are important circuits that can be employed in many radio frequency (RF) applications, e.g., in automatic gain control (AGC) amplifiers, broadband gain-control blocks at RF frequencies or as broadband vector modulators. For any applications, low insertion phase shift and low power consumption are of interest. LÄS MER

  4. 13. Study of The Electrical Properties of Pacemaker Leads

    Kandidat-uppsats, Ämnesavdelningen för elektronik

    Författare :Jomo Mengistu; [2008]
    Nyckelord :Pacemaker; Leads;

    Sammanfattning :   Abstract The purpose of this thesis is to examine the electrical properties of pacemaker leads by measurements and theoretical analysis. If time allows, recommendations on how to construct a simple circuit model to explain the phenomenon will be given based on the electrical properties obtained from measurements performed during the work of this thesis.

  5. 14. MEMS baserad referensoscillator

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Joel Hedestig; [2005]
    Nyckelord :Electronics; MEMS; MEMS-resonator; resonator; oscillator; reference oscillator; quartz crystal; Elektronik;

    Sammanfattning : The interest in tiny wireless applications raises the demand for an integrated reference oscillator with the same performance as the macroscopic quartz crystal reference oscillators. The main challenge of the thesis is to prove that it is possible to build a MEMS based oscillator that approaches the accuracy level of existing quartz crystal oscillators. LÄS MER
