This circuit measures the timing jitter, or variation, in the arrival time of a repetitive electrical signal of interest, such as from the output of a single-photon detector under short-pulse illumination. An ultra-low jitter clock that is synchronous with the repetition rate of the input signal is slowly swept in time (by some external means of phase delay) with respect to the input signal.

Temporal Jitter Analyzer And Analyzing Temporal Jitter

NIST Inventors
Joshua Bienfang
This is a simple method to measure the jitter, or temporal variation, of a repeated event. The method is based on simple electronic circuitry and can achieve measurement resolution on the order of hundreds of femtoseconds.
