A Method for Fault Diagnosis Based on Multidimensional Scaling (MDS) in Analog Circuits

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 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...

A Soft Fault-concept Diagnosis Method of Analog Circuits Based on Cloud Model Theory

As the component parameters of analog circuits are influenced by tolerance, a soft fault-concept diagnosis model in this paper, which is based on the qualitative concepts of cloud model theory, is proposed to achieve the complete description of fault states and the fast diagnosis. The diagnosis model uses the cloud transform method to represent the conceptual soft classification of the multiple...

A Fault Dictionary-Based Fault Diagnosis Approach for CMOS Analog Integrated Circuits

In this paper, we propose a simulation-before-test (SBT) fault diagnosis methodology based on the use of a fault dictionary approach. This technique allows the detection and localization of the most likely defects of open-circuit type occurring in Complementary Metal–Oxide–Semiconductor (CMOS) analog integrated circuits (ICs) interconnects. The fault dictionary is built by simulating the most l...
