SYSTEM AND METHOD FOR VOLTAGE NOISE AND JITTER MEASUREMENT USING TIME-RESOLVED EMISSION

摘要

Time-resolved emission can be used to measure loop-synchronous, small-signal voltage perturbation in integrated circuits. In this technique the measurements are completely non-invasive and so reflect the true device behavior. The time-dependant propagation delay caused by Vdd modulation also shows the expected qualitative signature. This technique should find applications in circuits with relatively fast clock-like circuits where loop-synchronous voltage pickup is limiting circuit behavior.
