  1. 1. 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

  2. 2. Investigation of Mechanisms for Spur Generation in Fractional-N Frequency Synthesizers

    University essay from Elektroniksystem; Tekniska högskolan

    Author : Sohail Imran Saeed; [2012]
    Keywords : DDSM; Digital Delta Sigma Modulator; EFM; Error Feedback Modulator; PLL Phase Locked Loop; Fractional N Frequency Synthesizer; Spur; Spurs;

    Abstract : With the advances in wireless communication technology over last two decades, the use of fractional-N frequency synthesizers has increased widely in modern wireless communication applications due to their high frequency resolution and fast settling time. The performance of a fractional-N frequency synthesizer is degraded due to the presence of unwanted spurious tones (spurs) in the output spectrum. READ MORE

  3. 3. Quantization Effects Analysis on Phase Noise and Implementation of ALL Digital Phase Locked-Loop

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

    Author : Jue Shen; [2011]
    Keywords : All Digital Phase-Locked Loop ADPLL ; Quantization Step; Non-linear quantization effect; Non-linear PLL noise model; Phase Noise; Matlab Modeling; Verilog Behavior Modeling.;

    Abstract : With the advancement of CMOS process and fabrication, it has been a trend to maximize digital design while minimize analog correspondents in mixed-signal system designs. So is the case for PLL. PLL has always been a traditional mixed-signal system limited by analog part performance. READ MORE

  4. 4. Modeling and Characterization of an All-Digital Phase-Locked Loop

    University essay from Institutionen för teknik och naturvetenskap

    Author : Alfred Johnson; Fredrik Andersson; [2010]
    Keywords : ;

    Abstract : The thesis "Modeling and Characterization of an All-Digital PLL" aims to create a behavioral model of an All-Digital Phase-Locked-Loop (ADPLL). The model should be able to perform accurate and time-effective simulations. Based on the model, a sub-block requirement will be presented as decision basis for test chip manufacturing. READ MORE
