DCO with a frequency resolution of 150Hz for All-digital PLL




FREE-DOWNLOAD L Fanori, A Liscidini… – Solid-State Circuits …, 2010 –
In all-digital phase-locked loops (ADPLLs), the quantization noise introduced by the frequency
discretization in the digitally controlled oscillator (DCO) can affect the performance in terms of
out-of-band phase noise. In particular, the addition- al quantization noise has to be kept
