1. 1. A digital integer-N PLL architecture using a pulse-shrinking TDC for mmWave applications.

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Simon Richter; [2023]
   Nyckelord :Phase-locked-loops; All-digital Phase-locked-loops; Time-to-digital converters; 5G and beyond; Radio-frequency design; Fas-låsd-loop; Helt-digital fas-låst-loop; Tid-till-digital-omvandlare; 5G och framtiden; Radio-frekvens design;

   Sammanfattning : With the move of the broadband cellular network towards 5G taking off and the preparatory work on 6G and beyond starting, the need for low-complexity, low-power, and high-performance frequency synthesis using Phase-Locked Loop (PLL)s increases. As we get deeper into the mm-wave frequencies and push towards frequencies in the order of 50-70 GHz design challenges with existing PLL architectures, such as limited technology scaling and limited in-band noise performance become more apparent.

3. 2. III-V Nanowire MOSFETs for mm-Wave Switch Applications

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

   Författare :Marcus Sandberg; [2020]
   Nyckelord :III-V Nanowire MOSFET; millimeter wave mmW ; millimeter-wave integrated circuit MMIC ; single-pole double-throw SPDT ; Technology and Engineering;

   Sammanfattning : RF-switches are key components in many electronic devices as they enable routing of higher frequency signals. Increasing demands on device performance requires new technologies as well as new approaches to designs of circuits. III-V nanowire MOSFETs are a promising device technology well suited for implementation of switches. LÄS MER

4. 3. Visible Light Communication as a material for design

   Master-uppsats, KTH/Människa-datorinteraktion, MDI

   Författare :Charles Windlin; [2016]
   Nyckelord :Interaction Design; Human Computer Interaction; Tinkering; Visible Light Communication; Materiality; Digital Material; Constructive Design Research; Prototyping.;

   Sammanfattning : Visible light communication (VLC) is a novel complement to Radio Frequency Communication (RFC) and has many applications in wireless communication, indoor positioning and where RFC is not applicable. The problem is that the technology is black-boxed and therefore hard to apply in today’s design process. LÄS MER

5. 4. Zigbee versus Radio Frequency Identification (RFID)

   Master-uppsats, Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

   Författare :Solomon Onoabhagbe; [2008]
   Nyckelord :ZigBee; RFID; Telecommunication; WPAN and Wireless Systems;

   Sammanfattning : The growth of Telecommunication in the world has brought about the need for regular update, research and findings, to meet the demands of the global world. With the rising demand of home automation and sensor network, the ZigBee protocol has been identified to target on low power devices, Personal Area Network (PAN) and sensor nodes. LÄS MER
