Abstract
The present disclosure relates to phase measurement circuitry operable based on a first clock signal having an intended clock frequency Fand a second clock signal having an intended clock frequency F, the circuitry comprising: a delay line configured to receive the first clock signal, the delay line comprising a plurality of delay units each configured to cause a propagation delay, and the plurality of delay units connected in series along the length of the delay line and defining a series of positions therebetween through which signal edges of the first clock signal propagate over time; an edge detector configured to sample the delay line at successive sample times based on the second clock signal and to record at each sample time the position of a given signal edge of the first clock signal along the delay line; and a phase angle determiner configured to determine a phase angle per delay unit based on successive recorded said positions.
