Fast frequency acquisition is crucial for phase-locked loops (PLLs) used in portable devices, as on-chip clocks are frequently scaled down or up in order to manage power consumption. This paper describes a new frequency acquisition method that is effective in all-digital PLLs (ADPLLs). To achieve fast frequency acquisition, the codeword of the digitally controlled oscillator (DCO) is predicted by measuring the variations of process, supply voltage and temperature (PVT).
