TIME-OF-FLIGHT ARRANGEMENT AND METHOD FOR A TIME-OF-FLIGHT MEASUREMENT
Abstract:
A time-of-flight arrangement (10) comprises a laser (15), a laser driver (12), a clock generator (11) that is coupled to the laser (15) via the laser driver (12), a photodiode circuit (50) and a time-to-digital converter (14). The photodiode circuit (50) comprises an avalanche photodiode (51), a quenching circuit (52), a diode node (53) and a readout circuit (54). The quenching circuit (52) is coupled via the diode node (53) to the avalanche photodiode (51). An input of the readout circuit (54) is connected to the diode node (53). At least one of the clock generator (11) and the readout circuit (54) is coupled on its output side to the input side of the time-to-digital converter (14).
