    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, Elektroniksystem; Tekniska 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
