Abstract

A droop detector includes: a plurality of input nodes, each input node configured to receive a supply voltage; an output node; a plurality of detector modules, each detector module comprises: an input terminal coupled to each input node, an output terminal coupled to the output node; and an input tracking unit configured as a voltage follower to detect a droop in the supply voltage coupled to each input node and output an output voltage that follows the supply voltage on the output terminal when the droop is detected on the supply voltage; and a comparator coupled to the output node and configured to output a control signal when the droop is detected.
