  1. 1. D-band Power Amplifiers in Vertical InGaAs Nanowire MOSFET Technology for 100 Gbps Wireless Communication

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Patrik Blomberg; Ludvig Pile; [2022]
    Keywords : D-band; Power Amplifier; Pseudo-differential common source; Stacked; Vertical InGaAs nanowire; MOSFET; Technology and Engineering;

    Abstract : Two different topologies of power amplifiers (PAs) are designed in the frequency range 130-174.8 GHz for use in backhaul transmitters. These are the pseudo-differential common source (PDCS) and the single-ended stacked amplifier topologies. READ MORE

  3. 2. Evaluation of Discrete-Time Wideband Receivers for NB-IoT

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Magnus Wasting; [2021]
    Keywords : Discrete; time; filter; NB-IoT; Charge; Sharing; CMOS; Technology and Engineering;

    Abstract : A receiver that covers several RF bands requires multiple front-end filters which increases the cost in terms of components and/or board/silicon area. Front-end filters assist a receiver to withstand interference at multiples of its down-conversion frequency. READ MORE

  4. 3. PLL for 5G mmWave

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Daniel Bakic; Jinzhuo Wu; [2020]
    Keywords : PLL; 5G-NR; RFIC; beamforming; 22nm FDSOI; charge pump; vco; loop filter; frequency divider; phase detector; phase noise; jitter; Technology and Engineering;

    Abstract : This paper presents research and implementation of a high frequency Integer-N phase-locked loop for digital beamforming in mobile devices. Multiple topologies investigated whereof two were implemented. The transient phase noise of the PLL is -104dB/-95dB @1MHz. The output frequency range is from 8G-10G. READ MORE
