Abstract
An offset compensation circuit comprises an error signal generation block arranged for receiving an input phase and an output phase, and for generating an error signal indicative of an error between the input phase and the output phase. Means are provided for combining the error signal with an offset compensation signal, yielding an offset compensated signal. A loop filter is arranged for receiving the offset compensated signal and for outputting the output phase. An offset compensation block is arranged for receiving the output phase and for determining the offset compensation signal. The offset compensation signal comprises at least a contribution proportional to a periodic function of the output phase.
