Abstract
A phase locked loop, particularly for or in a beamforming system comprises a loop filter () to provide a control signal (FC) to a controllable oscillator (); a frequency divider () configured to provide a first feedback signal (FB) and a second feedback signal (FBD) in response to an oscillator signal (FO), the second feedback signal (FBD) delayed with respect to the first feedback signal (FB); a first comparator path () configured to receive the first feedback signal (FB) and a second comparator path () configured to receive the second feedback signal (FBD), each of the first and second comparator path () configured to provide a respective current signal (CS, CS) to the loop filter () in response to a respective adjustment signal (FA, FA) and a phase deviation between a common reference signal (FR) and the respective feedback signal (FB, FBD).
