  1. 1. Electrical Pulsing of a Laser Diode for Usage in Fluorescence Microscopy

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Karin Jerner; [2017]
    Keywords : electrical pulsing; laser pulsing; fluorescence microscope; laser diode;

    Abstract : A relatively new application for the laser is in fluorescence microscopes. The fluo- rescence microscope needs a high power light source input. Using a laser source improves the precision of the microscope. A pulsed laser source enhances the performance of the fluorescence microscope and a laser diode can be overdriven without being damaged.

  2. 2. A High Efficiency and Wideband Doherty Power Amplifier for 5G

    University essay from Chalmers tekniska högskola/Institutionen för mikroteknologi och nanovetenskap

    Author : Halil Volkan Hünerli; [2017]
    Keywords : ;

    Abstract : In today’s wireless communications, mobile networks need high data rates and low power consumption. For this purpose, novel wideband and energy efficient power amplifiers should be designed. This thesis is concerned with this problem. READ MORE

  3. 3. Power-Efficient Settling Time Reduction Techniques for a Folded-Cascode Amplifier in 1.8 V, 0.18 um CMOS

    University essay from Linköpings universitet/Elektroniska Kretsar och SystemLinköpings universitet/Tekniska fakulteten

    Author : Jimmy Johansson; [2017]
    Keywords : Folded-Cascode; Settling Time; Settling Time Reduction; Slew Rate; Slew Rate Enhancement; Operational Amplifier; Recycling Folded-Cascode; 180 nm CMOS; Test Buffer; Power-Efficient; Single-Stage Amplifier; Linear Settling Period; Slewing Period;

    Abstract : Testability is crucial in today’s complex industrial system on chips (SoCs), where sensitive on-chip analog voltages need to be measured. In such cases, an operational amplifier (opamp) is required to sufficiently buffer the signals before they can drive the chip pad and probe parasitics. READ MORE

  4. 4. Words have power: Speech recognition in interactive jewelry : a case study with newcome LGBT+ immigrants

    University essay from Södertörns högskola/Medieteknik

    Author : Anton Poikolainen Rosén; [2017]
    Keywords : Interactive jewelry; speech recognition; wearable computing; affective computing; LGBT ; migration; LED-lights.;

    Abstract : This paper addresses a design exploration focusing on interactive jewelry conducted with newcome LGBT+ immigrants in Sweden, leading to a necklace named PoWo that is “powered” by the spoken word through a mobile application that reacts to customizable keywords triggering LED-lights in the necklace. Interactive jewelry is in this paper viewed as a medium with a simultaneous relation to wearer and spectator thus affording use on the themes of symbolism, emotion, body and communication. READ MORE

  5. 5. Energy Efficiency of Radio Units and its Impact on RAN Energy Consumption

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Thomas Berglund; Helen Huynh; [2017]
    Keywords : Energy efficiency; telecommunications; LTE; mobile networks; Technology and Engineering;

    Abstract : As mobile telecommunications networks continue to grow, energy consumption continues to grow with it. This will without a doubt affect both the operational expense for network operators and the environment due to air pollution from power stations. READ MORE
