  1. 1. 1kW Class-E solid state power amplifier for cyclotron RF-source

    University essay from Uppsala universitet/FREIA

    Author : Stefan Book; [2018]
    Keywords : Class-E; LDMOS; high efficiency; high power; VHF; power amplifier; accelerator; cyclotron;

    Abstract : This thesis discusses the design, construction and testing of a highefficiency, 100 MHz, 1 kW, Class-E solid state power amplifier. The design was performed with the aid of computer simulations using electronic design software (ADS). The amplifier was constructed around Ampleon's BLF188XR LDMOS transistor in a single ended design. READ MORE

    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

  4. 4. 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

  5. 5. 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
