Abstract
A detector circuit included in a computer system filters the voltage level of a power supply node to generate filtered signals. The detector circuit either compares the filtered signals or samples the filtered signal and compares the samples to reference levels to detect changes in the voltage level of the power supply node that exceed thresholds for magnitude and duration. A control circuit included in the computer system generates, using the glitch signal, control signals that can be used to change operating parameters of functional circuits included in the computer system.
