摘要：

The hardware structure and the data-processing flow of FPGA based Time to Digital Converter (TDC) are introduced firstly in the essay. Then, according to the issue of inaccuracy in arriving time of external triggers, a correction method is proposed to enhance the accuracy of starting time. In the end, by contrast experiment, it is shown that this correction method could improve the accuracy of starting time effectively. In addition, the minimum time resolution is 400ps, which makes the TDC be adequate for applications in the fields which require high-resolution time measurement, for example, in the application of time-of-flight mass spectrometer (TOF-MS).
