Abstract
A circuit arrangement for measuring a time interval by evaluating the number of complete cycles, and/or the fraction of a cycle, of a ring oscillator that occur(s) during the time interval to be measured, in which there are provided means to avoid a count ambiguity if the time interval ends at or about the completion of a cycle of the ring oscillator.
