Abstract

See full text

A circuit detects a voltage droop exhibited by a power supply. A first signal delay line outputs a first delayed signal, and is comprised of delay elements having a first threshold voltage. A second delay line outputs a second delayed signal, and is comprised of delay elements having a second threshold voltage that is higher than the first threshold voltage. A phase detector compares the first and second delayed signals and outputs a comparison signal indicating which of the first and second signal delay lines exhibits a shorter delay. A reset circuit resets the first and second signal delay lines in response to the comparison signal, and a clock controller outputs a command to adjust a clock frequency or engage in other mitigation measures based on the comparison signal.
