   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

   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
