Abstract
An apparatus for detecting an anomaly in an electronic system embodying at least two integrated circuits, and where necessary, removing/mitigating the anomaly. The anomaly detection is based on sensing the characteristics of either the current, the voltage, or both the current and voltage of the supply rail connected to the at least two integrated circuits. When an anomaly occurs, the anomaly is detected by one sensing circuit sensing that the characteristics are different from that when the electronic system is functioning normally.
