  1. 1. Current-Mode Class D Power Amplifier for 2.4GHz Wi-Fi

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

    Författare :Yann Jean Michael Pirot; [2023]
    Nyckelord :Power Amplifier; Wifi; Digital Power Amplfier; Class D; RFIC; Analogue; Effektförstärkare; Wifi; digital förstärkare; klass D; analog;

    Sammanfattning : Modern wireless communication techniques employed in the Wi-Fi® protocol, such as orthogonal frequency-division multiplexing exhibit analogue signals with high peak-to-average power ratio. Therefore, power amplifiers for Wi-Fi suffer from low efficiency when operating in back-off mode, away from their maximum efficiency at peak power. LÄS MER

  3. 2. Development of III-V RF Nanowire MOSFETs

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

    Författare :Josefine Rost; Anna Wagnström; [2018]
    Nyckelord :Nanowire MOSFET; RF; COMSOL Multiphysics; Semiconductor processing; III-V Materials; Technology and Engineering;

    Sammanfattning : The silicon MOSFET is one of the most important components used in modern electronics. The pursuit to continue fulfilling Moore’s law by scaling transistors to even smaller sizes have driven the development forward for CMOS technologies and new approaches have been necessary. LÄS MER

  4. 3. A 65nm, Low Voltage, Fully Differential, SC Programmable Gain Amplifier for Video AFE

    Master-uppsats, Linköpings universitet; Institutionen för systemteknik

    Författare :Syed Ahmed Aamir; [2010]
    Nyckelord :video; analog; low voltage; SC; CMFB; OTA; PGA;

    Sammanfattning : Due to rapid growth of home entertainment consumer market, video technology has been continuously pushed to deliver sharper pictures with higher resolution. This has brought about stringent requirements on the video analog front end, which often coupled with the low power and low voltage regulations had to deal with short channel effects of the deep submicron CMOS processes.

  5. 4. Konstruktion av förstärkare och insamplingssteg till en PSAADC i 0.25 um CMOS

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Martin Andersson; [2002]
    Nyckelord :Electronics; ADC; SAADC; PSAADC; OP; miller-op; OTA; voltage references; tvåstegsförstärkare; Elektronik;

    Sammanfattning : The aim and goal of this work has been to design and implement a voltage reference network for a 12-bit PSAADC, Parallell Successive Analog to Digital Converter. A chip containing the design has been sent away for fabrication. Because of the long processing time, no measurement data are presented. LÄS MER
