Abstract
Disclosed is a digital voltage regulator system and method for mitigating voltage droop in an integrated circuit. If an unacceptable voltage droop is detected, the digital voltage regulator may take action to allow the power supply voltage to recover. A digital voltage regulator in accordance with embodiments discussed herein detects voltage droop by comparing a power supply voltage measurement with a threshold voltage. The threshold voltage may be calibrated based on power supply voltage measurements taken while the integrated circuit is operating.
