Abstract

A time-to-digital converter arrangement has a ring oscillator with a plurality of inverting elements and a first and a second counter coupled to the ring oscillator. The first counter is configured to increment a first counter value if a positive edge transition is present at one of the inverting elements. The second counter is configured to increment a second counter value if a negative edge transition is present at the one of the inverting elements. A storage element stores the first and the second counter value and logical states of the plurality of inverting elements. A decoder coupled to the storage element selects one of the first and the second counter value as a valid value based on an evaluation of the stored logical states, and outputs a total counter value based on the valid value and the stored logical states.
