  4. 3. Ultra-low power circuits for power management

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Giuseppe Forestiere; [2014]
    Nyckelord :;

    Sammanfattning : Recent developments in energy harvesting techniques allowed implementation of completely autonomous biosensor nodes. However, an energy harvesting device generally demands a customized power management unit (PMU) in order to provide the adequate voltage supply for the biosensor. One of the key blocks within this PMU is a regulation DC-DC converter. LÄS MER
