FAULT DETECTION AND DIAGNOSIS OF ANALOG CIRCUIT USING SOFT COMPUTING TECHNIQUE BASED ON SUPPLY CURRENT AND OUTPUT VOLTAGE

Abstract

Circuit fault diagnosis is an important area for electronic manufacturing industries. For critical applications, it is desired to design & develop the system that will detect the fault appearing condition by analyzing various circuit parameters in real time. It is proposed to analyze circuit parameters like supply current and output voltage of circuit under test (CUT). From these parameters it is possible to identify the deviation in performance of the circuit. By using the soft computing technique, it is possible to identify the fault & to diagnose it.
