The present invention relates to a time-to-digital converter (100) having a self-calibrating n-stage chain of a number n of propagation delay elements (50) which are parallel-series connected betweena clock signal line (12) for supplying a clock signal (16) and a stop signal line (13) for supplying a stop signal (17), and a charge pump and phase detector unit (10) for feedback control of the propagation delay elements (50) with a first input (10-1) as the controlled variable input, a second input (10-2) as the reference variable input, and an output (10-3) as the command variable output. Theclock signal line (12) is connected to the first input (10-1) of the charge pump and phase detector unit (10), a push-pull line (14) for supplying a push-pull signal (18) is connected to the second input (10-2), and the propagation delay elements (50) are connected to the output (10-3) of the charge pump and phase detector unit (10) for feedback.
