1. 1. Characterization of an ADC

   Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

   Författare :Carl-Fredrik Tengberg; [2017]
   Nyckelord :;

   Sammanfattning : Analog-to-Digital converters, ADCs, introduces the possibility of performing digital computation on real world analog signals by being the interface between thetwo domains. The demands on the performance of the ADC is steadily increasing, which also comes with an increased difficulty of actually being able to guarantee the functionality of the device. LÄS MER

3. 2. Low Power Current Sensing Node Powered by Harvested Stray Electric Field Energy

   M1-uppsats, Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Tekniska fakulteten

   Författare :Björn Holby; Carl-Fredrik Tengberg; [2015]
   Nyckelord :Energy Harvesting; Low Power; Sensor; Wireless Communication;

   Sammanfattning : In this thesis, the possibility of harvesting energy from a multicore power cableconnected to a power outlet is presented and evaluated. By surrounding a powercable with a conductive material connected to ground, it is shown that the dif-ference in potential between the power cable and the conductive material causesa capacitance which can charge a capacitor that in combination with an energymanagement circuit can be used to wirelessly transmit data with an interval de-pending on factors like the length of the surrounding material and the type ofcable it is placed around.
