Abstract
A time-to-digital converter circuit is disclosed, the time-to-digital converter circuit including a plurality of delay stages connected to form a delay line, a plurality of event counters, an encoder circuit for triggering the delay line, and a binning circuit for associating an event with an event counter from plurality of event counters. The binning circuit selects the event counter based on a signal from the delay line, and wherein the encoder circuit is configured to sequentially trigger a different delay stage of the plurality of delay stages. Also disclosed is a time-of-flight sensor implementing the time-to-digital converter circuit, and an associated apparatus and method.
