1. A multi-shot time-to-digital converter comprising:
a time-to-digital conversion circuit; and
a timing control circuit coupled to the time-to-digital conversion circuit and sending a start signal to the time-to-digital conversion circuit multiple times for measuring a time interval corresponding to the start signal;
wherein the time-to-digital conversion circuit obtains a fine phase time based on a plurality of clock signals to measure the time interval and provides a plurality of time-to-digital codes for digital processing, the phases of the clock signals are different.
