“…f V is the generated variable frequency output; f R is the input reference frequency. The fractional spurs are fundamentally due to the finite quantization of the phase detection mechanism [e.g., time-to-digital converter (TDC) resolution] and were first studied in [3]. Furthermore, TDC imperfections, such as wrong estimation of its gain as well as its non-linearities can worsen the fractional spurs.…”

“…No caso dos PLL digitais, têm se estudado métodos de otimização, considerando redes de PLLs e a sua interconexão (Orsatti, Carareto e Piqueira, 2008), (Carareto, Orsatti e Piqueira, 2009). Também se têm analisado o ruído e a sincronização de redes de PLLs totalmente digitais (Vamvakos, Staszewski, Sheba e Waheed, 2006), (Akre and, Juillard, Galayko e Colinet, 2010).…”

“…Furthermore, the DCO quantization error cannot be filtered by the loop due to its high-pass transfer function. The shortterm quantization error of the DCO will be sampled back to the loop and amplified due to gain variation of the TDC [9], resulting in spurs.…”
