Time stamping events for fractions of a clock cycle |
摘要 |
Generally, the embodiments are directed to circuits and methods for time stamping an event at a fraction of a clock cycle. A time stamping circuit comprises two or more detection circuits. The detection circuits receive an event-in signal and generate event signals based on a clock phase at which the event-in signal was received. A decoder receives the event signals and outputs an event-out signal and a time stamp that represents the phase at which the event-in signal was detected. By time stamping the event-in signal to a phase division, the time stamping circuit detects event signals that occur at a rate faster than the clock cycle.
