| 摘要 |
The invention relates to a time-to-digital converter comprising: a first input (300) for receiving a first digital signal (A) having a first pulse duration; a second input (310) for receiving a second digital signal (B) having a second pulse duration, said first digital signal (A) and said second digital signal (B) having an overlapping pulse duration and non-overlapping pulse durations; a delay chain comprising several pulse delaying components (330.1-330.n) for time measuring, and an output (351) for outputting a time signal representing the difference between the first pulse duration (TA) and the second pulse duration (TB). Further, the inventive time-to-digital converter is characterized in that said delay chain (330.1-330.n) measures both non-overlapping pulse durations, so that no duplication of the delay chain is necessary.
