Abstract
An integrated circuit includes a digital logic circuit having a first transistor and a second transistor, a replica circuit having a first transistor and a second transistor which replicate the first transistor and second transistor of the digital logic circuit, and a storage circuit configured to store a static state indicator. The circuit also includes a comparison circuit configured to compare threshold voltages of the first and second transistor of the replica circuit, and having an output coupled to provide the static state indicator to the storage circuit, and a selection circuit configured to provide the state indicator to an input of the digital logic circuit and an input of the replica circuit during a lower power mode and to provide a run mode signal instead of the state indicator to the input of the digital logic signal and the input of the replica circuit during a high power mode.
