Summary:The invention relates to protection of integrated circuits from attacks using voltage monitoring. An integrated circuit (IC) includes a functional circuit and an attack protection circuit (APC). The functional circuit is configured to receive a power voltage from a power input. An APC is coupled to the power supply input and includes a front-end circuit and an averaging circuit. The front-end circuit is configured to compare the supply voltage to a plurality of voltage thresholds and output a respective plurality of indications indicating whether the supply voltage violates a respective voltage threshold. The averaging circuit is to estimate, for a selected subset of the indications, a respective duty cycle of the subset indicating that a respective voltage threshold is exceeded. The APC is to trigger one or more attack detection events in response to the indication and the duty cycle. 本发明涉及使用电压监控保护集成电路免受攻击。集成电路(IC)包括功能电路和攻击保护电路(APC)。功能电路用于接收来自电源输入的电源电压。APC耦合到所述电源输入，并且包括前端电路和平均电路。前端电路用于将电源电压与多个电压阈值进行比较，并输出指示电
