Abstract
A self-referenced on-die voltage droop detector generates a reference voltage from the supply voltage of an integrated circuit's power distribution network, and compares this reference voltage to the transient supply voltage in order to detect voltage droops. The detector responds to detected occurrences of voltage droop with low latency by virtue of being located on-die. Also, by generating the reference voltage from the integrated circuit's power domain rather than using a separate reference voltage source, the detector does not introduce noise and distortion associated with a separate power domain.
