Abstract:In the memory cells of the analogue switched circuits, there are some types of faults which are very difficult to detect using either voltage or current based test methods. However, it is possible to detect these faults by means of the changes in the slope of the dynamic current supply, IDDT. In this work, we present a Built-In Current Sensor (BICS) which is able to process the highest frequency components in the dynamic current supply of the circuit under test (CUT). The BICS uses an inductance made from a gyrator and a capacitor to carry out the current to voltage conversion. Moreover, the proposed test method improves the fault coverage in continuous circuits, as can be seen when it is applied to the detection of faults in an operational amplifier.
