Empirical Investigation of Genetic Algorithm Parameters on Neural Network based Fault Diagnosis in Analog Circuits

Divya Bisen, Yogesh Sharma


Fault analysis in analog circuit is matter of research since last few decades because of the complexity in diagnosis of fault models. This paper proposes fault diagnosis approach for analog circuit using hybrid evolutionary techniques and neural network. Neural network is used because of its good robustness and adaptability and genetic algorithm is used as evolutionary technique for optimization and learning of neural network. The proposed method is validated through state variable filter circuit and all possible parametric variations are taken for faulty and non-faulty condition and experimental results are presented to show that hybrid scheme is more efficient than neural network method.
