<p>A time-to-digital converter (110) comprising at least one chain of delay elements (126.1,..., 126.N), wherein a status of said chain of delay elements (126.1,..., 126.N) represents a digital signal relating to a time interval to be converted, wherein said time- to-digital converter (110) comprises means (156) for providing trigger signals (154) having statistically equally distributed variable positions relative to a pulse forwarded in said chain of delay elements (126.1,..., 126.N), means (130) for capturing said status of said chain of delay elements (126.1,..., 126.N) in response to said calibration trigger signals (154), wherein said status depends on delay times of said delay elements (126.1,..., 126.N), means for determining an actual contribution of at least some of said delay elements (126.1,..., 126.N) to an overall delay of said chain of delay elements (126.1,..., 126.N) on the basis of occurrences of pulse positions in response to said calibration trigger signals (154), and means (164) for taking into account said actual contribution of at least some of said delay elements (126.1,..., 126.N) when converting said time interval into said digital signal (168).</p> |
