Abstract

One of the challenges of testing at multiGbps rates is jitter characterization. This article introduces a new technique that allows for attaining on-chip measurements at a substantial level of accuracy. The authors propose new algorithms that allow a wide frequency range, supporting the desired accuracy while guaranteeing signal integrity and low overhead.
