摘要：
The present invention relates to an offset compensation circuit comprising
- an error signal generation block (10) arranged for receiving an input phase ( θ i ) and an output phase ( θ o ) and for generating an error signal indicative of an error between said input phase and said output phase,
- means (20) for combining said error signal with an offset compensation signal, yielding an offset compensated signal,
- a loop filter (30) arranged for receiving said offset compensated signal and for outputting said output phase ( θ o ),
- an offset compensation block (40) arranged for receiving said output phase ( θ o ) and for determining said offset compensation signal, said offset compensation signal comprising at least a contribution proportional to a periodic function of said output phase.
