  1. 1. Evaluation of Discrete-Time Wideband Receivers for NB-IoT

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

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

    Sammanfattning : 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. LÄS MER

  4. 3. Direct Conversion Front End for LTE and LTE-A with Frequency-Translational Feedback, Harmonic Rejection Mixer and Input Matching Compensation

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

    Författare :Douglas Andersson Hägglund; [2016]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This thesis covers the design of a wideband, flexible front end for LTE and LTE-A in a 65 nm CMOS process. A topology with global frequency translational feedback is investigated and a harmonic rejection mixer is implemented. LÄS MER

  5. 4. Investigation of Control Approaches for a High Precision, Piezo-Actuated Rotational Stage

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Niklas Ericson; [2016]
    Nyckelord :Rotational stage; Piezoelectric actuator; Integral resonance control; Adaptive control; External disturbance rejection; Harmonic cancellation;

    Sammanfattning : The Equipment Controls and Electronics section (EN-STI-ECE) at CERN is developing a high precision piezo-actuated rotational stage for the UA9 crystal collimation project. This collaboration is investigating how tiny bent crystals can help to steer particle beams used in modern hadron colliders such as the Large Hadron Collider (LHC). LÄS MER

  7. 5. Inductorless LNA and Harmonic-rejection Mixer for Wideband Direct-conversion Receiver

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

    Författare :Anh Chu; [2015]
    Nyckelord :Ericsson; inductorless; harmonic-rejection; Noise-cancelling LNA; Mixer; LNA; Receiver; LTE-A; 4G Network; Technology and Engineering;

    Sammanfattning : In this master thesis, combinations of noise-canceling LNA and harmonic-rejection mixers are investigated and compared to find an optimal inductorless receiver front-end for low-band (600-960MHz) FDD LTE-A network. The work was carried out in a modem development project at Ericsson Modems, Lund. LÄS MER
