Abstract :
We propose a monitor able to detect on-line excessive power supply noise (PSN) at the power/ground lines. It has high resolution (100 ps), enough to collect the important features of PSN and its output is isolated from the local PSN. It is useful for any scheme that takes corrective actions to prevent signal integrity faults after detection of excessive PSN.
