Abstract
A detector () detects an event. First and second time-to-digital converters (TDCs) () generate first and second time stamps (TS, TS) for the detection of the event. The first TDC and the second TDC are both synchronized with a common clock signal () that defines a fixed time offset between the second TDC and the first TDC. An autocalibration circuit () adjusts the first TDC and the second TDC to keep the time difference between the second time stamp and the first time stamp equal to the fixed time offset between the second TDC and the first TDC. The detector may be a detector array, and trigger circuitry () propogates a trigger signal from a trigger detector of the array of detectors to the first and second TDC's. Skew correction circuitry () adjusts a timestamp (TS) based on which detector is the triggering detector.
