Abstract

The present disclosure provides a time-to-digital (TDC) converter, comprising: a coarse TDC receiving a start signal and a stop signal, delaying the first start signal in a first time unit to generate n first delayed start signals (where n is an integer equal to or larger than 2), measuring a time difference between the first delayed start signal and the stop signal in the first time unit, and generating second delayed start signals that are obtained by delaying the first delayed start signals in a time unit shorter than the first time unit; and a fine TDC receiving and delaying the second delayed start signal generated from the coarse TDC and receiving the stop signal, and measuring a time difference between the second delayed start signal and the stop signal in a second time unit.
