  1. 1. System Level Modeling and Verification of All-digital Phase-locked Loop

    Kandidat-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Chi Zhang; [2015]
    Nyckelord :;

    Sammanfattning : In wirelesscommunication systems, a local oscillator (LO) aims at demodulating radio-frequency signals into baseband signals. The performance of these signals determines the quality of communications which is highly affected by the phase accuracy of local oscillators. LÄS MER

  2. 2. Construction of a low-ripple inverter with accurate phase control for calibration of measurement equipment

    H-uppsats, Chalmers tekniska högskola/Institutionen för energi och miljö

    Författare :Adam Einarsson; Ali Asgari Vand; [2014]
    Nyckelord :PWM; full-bridge converter; IGBT; CompactRIO™; Kalman filter; PLL.;

    Sammanfattning : For the design of an electric power system, knowledge of the parameters of all the componentsis essential. Especially the transformers are an important part of this. It is thereforeimportant that the measurement equipment for determining these values is accurate. Inno-load operation, the transformer mainly consumes reactive power. LÄS MER

  3. 3. Design and Simulation of Miscellaneous Blocks of an All-Digital PLL for the 60 GHz Band

    Master-uppsats, Linköpings universitet/Linköpings universitet/ElektroniksystemTekniska högskolan; Linköpings universitet/Linköpings universitet/ElektroniksystemTekniska högskolan

    Författare :Hadiyah Butt; Manjularani Padala; [2013]
    Nyckelord :ADPLL; PLL; DCO; TDC;

    Sammanfattning : A phase-locked loop commonly known as PLL is widely used in communication systems. A PLL is used in radio, telecommunications, modulation and demodulation. It can be used for clock generation, clock recovery from data signals, clock distribution and as a frequency synthesizer.Most electronic circuits encounter the problem of the clock skew. LÄS MER

  4. 4. Design of a Time-to-Digital Converter for an All-Digital Phase Locked Loop for the 2-GHz Band

    Master-uppsats, Linköpings universitet/Linköpings universitet/ElektroniksystemTekniska högskolan; Linköpings universitet/Linköpings universitet/ElektroniksystemTekniska högskolan

    Författare :Naveen Wali; Balamurali Radhakrishnan; [2013]
    Nyckelord :ADPLL; TDC; DPLL; PLL;

    Sammanfattning : An all-digital phase locked loop for WiGig systems was implemented. The developedall-digital phase locked loop has a targeted frequency range of 2.1-GHz to2.5-GHz. LÄS MER

  5. 5. Design of a DCO for an All Digital PLL for the 60 GHz Band : Design of a DCO for an All Digital PLL for the 60 GHz Band

    Master-uppsats, Linköpings universitet/Linköpings universitet/ElektroniksystemTekniska högskolan; Linköpings universitet/Linköpings universitet/ElektroniksystemTekniska högskolan

    Författare :Manikandan Balasubramanian; Saravana Prabhu Vijayanathan; [2013]
    Nyckelord :DCO; 65 nm; Oscillator; Varactor; Jitter; Differential to single; All-digital PLL; PLL;

    Sammanfattning : The work was based on digitally controlled oscillator for an all-digital PLL in 65nm process. Phase locked loop’s were used in most of the application for clock generation and recovery as well. As the technology grows faster in the existinggeneration, there has to be quick development with the technique. LÄS MER
