IC Sub-Threshold IDDQ Signature and Its Application to Hardware Security
A sub-threshold quiescent current (IDDQ) signature is observed for the first time. Oscillators (ROs) are used to study a characteristic knee/peak for different device types and threshold voltages undergoing different stress conditions. The relationship of the sub-threshold IDDQ characteristics to process variability and aging are explained with detailed circuit level simulations. This novel signature has potential applications for reliability and counterfeit (re-used) circuit detection.
