Abstract
An all-digital phase locked loop (ADPLL) is provided. The ADPLL comprises a pattern generator adapted to generate a frequency control word (FCW) based on a predefined setting and a system clock. In addition, the ADPLL comprises a phase accumulator adapted to translate the FCW into a phase trajectory. The ADPLL further comprises a phase comparator adapted to generate a phase error signal representing a difference between the phase trajectory and the phase of an output oscillation frequency. Moreover, the ADPLL comprises a controller adapted to control a phase of the output oscillation frequency with respect to the phase trajectory.
