Abstract :
A new method using power supply current spectrum phase components for fault detection in analogue and mixed mode circuits is presented. A procedure is introduced, a discrimination factor is defined and its value is adjusted for efficient application of the method. Representative results from an operational amplifier and a flash analogue-to-digital converter circuit are given, showing the effectiveness of the proposed method.
