Abstract
Examples include a sensor for estimating the operating age of an integrated circuit experiencing performance degradation and a related tamper detection method. The sensor is operable in a regular use mode or in a readout mode and includes a performance monitor responsive to temperature stress and voltage stress, and an anneal monitor responsive to temperature stress. The performance monitor is configured to receive an operating voltage of the integrated circuit when the sensor is operated in the regular use mode. Each anneal monitor is a pre-stressed monitor, and each performance monitor and each anneal monitor is configured to generate an output signal indicative of the performance degradation for the respective monitor when the sensor is operated in the readout mode.
