Abstract
In an embodiment, a method includes filtering, with a low-pass filter, a voltage signal (V) of a chip to create a filtered signal (V). The method further includes dividing Vby a given factor. The method further includes determining whether a voltage droop occurred in Vby comparing Vto the divided V. The method further includes outputting a droop detection signal if Vis less than the divided V. In an embodiment, dividing Vby the given factor includes selecting, with a multiplexer, one of a plurality of divided Vsignals outputted by a voltage divider. The selecting is based on a selection signal.
