Abstract
An integrated circuit having a frequency generator connected to a constant reference voltage source located on the integrated circuit and a monitor connected to monitor the frequency signal and from the frequency history predicting that an integrated circuit failure will occur. An adaptive power supply is disclosed that includes a frequency generator connected to a bandgap voltage source and is monitored for changes in the frequency generator output. From this change a prediction is made as to that a failure condition will occur.
