ABSTRACT:
The present invention is related to method and apparatus for on-die noise detection that includes one more voltage noise sensors, and one or more associated comparators. The voltage noise sensor includes a circuit including devices designed to position an initial voltage level of nodes between the devices at certain levels. The nodes are paired where the initial level of one node is above the initial level of the other node in the pair. The devices are designed to position the initial voltage levels of nodes of each pair such that the occurrence of noise above a predefined threshold voltage causes at least one of the voltage levels at the pair of nodes to approach and pass the other. The comparator monitors the voltage levels of each pair of nodes and generates a trigger signal upon detection of the voltage levels at a pair of nodes passing each other.
