Abstract: Time-to-digital converter system including: an event detector configured for detecting an event and generating an event detection signal upon detection of the event; and a time-to-digital converter coupled or connectable to the event detector and including a fine resolution part configured for counting fine time intervals, organized such that the fine resolution part is activated in response to the event detection signal and deactivated in response to a reference clock. 3D imager including an array of pixels, with in each pixel such a time-to-digital converter system, and further including a reference clock generator.

Abstract: 3D imager including at least one pixel, each pixel including a photodetector for detecting photon incidence and a time-to-digital converter system configured for referencing the photon incidence to a reference clock, and further including a reference clock generator provided for generating the reference clock, wherein the reference clock generator is configured for adjusting the frequency of the reference clock on the basis of an estimated time up to a subsequent photon incidence.
