Fault Diagnosis for Analog Circuits by Using EEMD, Relative Entropy, and ELM

This paper presents a novel fault diagnosis method for analog circuits using ensemble empirical mode decomposition (EEMD), relative entropy, and extreme learning machine (ELM). First, nominal and faulty response waveforms of a circuit are measured, respectively, and then are decomposed into intrinsic mode functions (IMFs) with the EEMD method. Second, through comparing the nominal IMFs with the...

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 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 ...
