Abstract :
A built-in sensor based on the detection of highest frequency components of the dynamic current supply of the circuit under test is proposed. In analogue SI circuits, there are faults difficult to detect using conventional test methods. It is possible to detect these faults by the changes in the slope of the dynamic current supply.
