Timing Jitter Characterization for Mixed-Signal Production Test Using the Interpolation Algorithm

In this paper, a jitter measurement circuit for mixed-signal production test based on the interpolation algorithm is presented. By utilizing the limited sampling points per cycle, the original signal under test is reconstructed with a high accuracy. From the reconstructed signal, most timing jitter features can be characterized. To validate the design effectiveness, comparative studies have been performed between this jitter measurement method and other standard jitter characterization instruments
