Abstract
A voltage droop detector captures the very high-frequency noise on the power grid of a load, such as a microprocessor. The droop detector includes twin circuits, one of which receives the voltage from the power grid of the load, the other of which receives a filtered voltage. A 0droop, as well as 1droops, 2droops, and so on, are captured and stored for subsequent analysis. The circuits sample the voltages frequently enough to ensure that all droop events are captured. Other embodiments are described and claimed.
