  1. 1. Phase Locked Loops in Fully Integrated NB-IoT Transceivers

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Adam Waks; [2018]
    Nyckelord :Phase locked loops; Narrow Band Internet of Things; Frequency pulling; Balun; Inductor; Technology and Engineering;

    Sammanfattning : This thesis investigates how to fulfill the Narrow Band - Internet of Things (NB-IoT) specification for a fully integrated transceiver in the phase locked loop's (PLL) perspective. Designing a fully integrated transceiver, integrating a power amplifier (PA) is challenging as it leads to frequency pulling of the voltage controlled oscillator (VCO) in the PLL, deteriorating the performance.

  3. 2. ‘Indio naciste, indio te quedás’: Las voces narrativas y los efectos narrativos desde una perspectiva sociocultural en Balún Canán

    Kandidat-uppsats, Lunds universitet/Spanska; Lunds universitet/Utbildningsvetenskap

    Författare :Jenny Svensson; [2018]
    Nyckelord :Rosario Castellanos; Balún-Canán; perspectiva infantil; indigenismo; infidencia; autor implícito; focalización; Languages and Literatures;

    Sammanfattning : La intención de este trabajo es investigar las voces narrativas en la novela mexicana Balún Canán (1968), escrita por Rosario Castellanos. En esta novela existen dos instancias narrativas diferentes: una niña narradora que narra en primera persona la primera y tercera parte, y un narrador anónimo que narra la segunda parte en tercera persona.

  4. 3. The Design and Linearization of 60GHz Injection Locked Power Amplifier

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Luhao Wang; [2016]
    Nyckelord :Power Amplifier; Injection-locking; Adaptive biasing; predistortion; Technology and Engineering;

    Sammanfattning : The RF power amplifier is one of the most critical blocks of transceivers, as it is expected to provide a suitable output power with high gain, efficiency and linearity. In this paper, a 60-GHz power amplifier based on an injection locked structure is demonstrated in a standard 65 CMOS technology. LÄS MER

  5. 4. Printed Antennas on Paper

    Master-uppsats, Avdelningen för elektronikkonstruktion

    Författare :Reza Moossavi; [2013]
    Nyckelord :Conductive ink; paper; antenna design; microstrip antenna; dipole; Itoh s balun;

    Sammanfattning : Ink-jet printing (IJP) using conductive inks, has gained the attention of scientistsand researchers during the past decades. Solar Cells (SCs), Radio FrequencyIdentication (RFID), E-papers and antennas are only some of the applicationsfor which IJP is being applied. IJP facilitates printing complex antenna structureswith a good resolution. LÄS MER

  7. 5. RFID Tag : RFID tag positioning and identification by using infrared and visual wavelength

    Kandidat-uppsats, Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Författare :Ender Gülerman; [2012]
    Nyckelord :RFID; Positioning; Image analysis; video processing; PCB; EMC; Balun;

    Sammanfattning : This thesis project aims to develop an active Radio Frequency Identification tag (RFID) which uses an interesting method for positioning and ID detection. In this project, rather than classical ways of positioning methods such as triangulation or radio maps, infrared light and a camera with an infrared filter was used for the positioning. LÄS MER
