Abstract
Traditionally, time stamp circuits have been used for precise digital time measurements. The resolution of these types of circuits, though, was generally limited by clock speed. Here, an apparatus is provided that performs time stamp operations and is not generally limited by clock speed. This apparatus generally uses an interpolator, counter, lathing circuits, and a synchronizer. Typically, the interpolator provides a residue signal to the synchronizer, and the synchronizer can determines whether to add the interpolation signal to a counter state based at least in part on a comparison of an event signal and the residue signal.
