Abstract

A circuit and method for providing a digital output indicative of the time at which an event occurred is disclosed. In one aspect, the circuit includes a fine timing circuit configured to determine in which sub-interval of a clock period the event occurred, and a correction circuit configured to correct an erroneous offset between a first and second clock signals in the fine timing circuit. The correction circuit includes a synch circuit configured to determine in which half of the clock period the event occurred so as to correct for erroneous offset in the fine timing circuit.
