  1. 16. Digitally Controlled Oscillator for mm-Wave Frequencies

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

    Author : Rikard Gannedahl; Johan Holmstedt; [2018]
    Keywords : RF; RFIC; oscillator; DCO; mm-wave; Technology and Engineering;

    Abstract : In the fifth generation of mobile communication, 5G, frequencies above 30 GHz, so-called millimeter-wave (mm-wave) frequencies are expected to play a prominent role. For the synthesis of these frequencies, the all-digital phase locked loop (ADPLL) has recently gained much attention. READ MORE

  3. 17. A Differential Measurement Probe with High Common Mode Rejection

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Björn Franzén; [2018]
    Keywords : Common mode rejection; Fiber-optic measurement probe; Current Sensing; High voltage measurements; Optical isolation; Technology and Engineering;

    Abstract : Measuring signals with high frequency common mode components are typically prone to measurement errors due to low common mode rejection at high frequencies. The purpose of this master thesis is to design a measurement probe that presents sufficient common mode rejection to measure current on high voltage motor drives directly at the switching stage, before filtering.

  4. 18. Analog Baseband Implementation of a Wideband Observation Receiver for RF Applications

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Gustaf Svensson; [2016]
    Keywords : observation receiver RF IC analog baseband digital pre-distortion feedback;

    Abstract : During the thesis, a two-staged analog baseband circuit incorporating a passive analog filter and a wideband voltage amplifier were successfully designed, implemented in an IC mask layout in a 65nm CMOS technology, and joined with a previously designed analog front-end design to form a wideband observation receiver. The baseband circuit is capable of receiving an IF bandwidth up to 990MHz produced by the analog front-end using low-side injection. READ MORE

  5. 19. Machine Learning for PAPR Distortion Reduction in OFDM Systems

    University essay from KTH/Signalbehandling

    Author : Manish Sonal; [2016]
    Keywords : Index Terms- OFDM; machine learning; PAPR; neural networks;

    Abstract : The purpose of the project is to investigate the possibility of using modern machine learning to model nonlinear analog devices like the Power Amplifier (PA), and study the feasibility of using such models in wireless systems design. Orthogonal frequency division multiplexing (OFDM) is one of the most prominent modulation technique used in several standards like 802. READ MORE

  6. 20. Architecture Designfor Compressed Sensing-Based Low Power Systems

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Giovanni Zamolo; [2016]
    Keywords : ;

    Abstract : In the Internet of Things scenario, a desirable feature of wireless sensors is the energy autonomy. However, the transmitter stage needs a great amount of energy to modulate and transmit the interested information. READ MORE
