    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

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

    University essay from Elektroniksystem; Tekniska högskolan

    Author : Hadiyah Butt; Manjularani Padala; [2013]
    Keywords : ADPLL; PLL; DCO; TDC;

    Abstract : 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. READ MORE
