Fault Diagnosis of Analog Circuits Using Extension Genetic Algorithm

This paper proposed a new fault diagnosis method based on the extension genetic algorithm (EGA) for analog circuits. Analog circuits were difference at some node with the normal and failure conditions. However, the identification of the faulted location was not easily task due to the variability of circuit components. So this paper presented a novel EGA method for fault diagnosis of analog circ...

A Method for Multiple Fault Diagnosis in Analog Circuits

---Fault diagnosis of analog circuits is essential for analog and mixed-signal circuits testing and maintenance. In this paper, a new method for multiple fault diagnosis in linear analog circuits is proposed based on the large change sensitivity analysis and ambiguity group locating technique. Test equation establishes the relationship between the measured responses and deviations of faulty par...

Kalman Filter Based Method for Fault Diagnosis of Analog Circuits

This paper presents a Kalman filter based method for diagnosing both parametric and catastrophic faults in analog circuits. Two major innovations are presented, i.e., the Kalman filter based technique, which can significantly improve the efficiency of diagnosing a fault through an iterative structure, and the Shannon entropy to mitigate the influence of component tolerance. Both these concepts ...

A generalized fault diagnosis in dynamic analog circuits

Fault diagnosis of analog circuits is essential for analog and mixed-signal systems testing and maintenance. A new method is proposed in this paper for multiple fault diagnosis of linear analog circuits in frequency domain. Woodbury formula is applied to the modified nodal equation to construct the fault diagnosis equation, which relates the limited measured circuit responses with the multiple ...
