Diagnosis Method for Analog Circuit Hard Fault and Soft Fault
Because the traditional BP neural network slow convergence speed, easily falling in local minimum and the learning process will appear oscillation phenomena. This paper introduces a tolerance analog circuit hard fault and soft fault diagnosis method based on adaptive learning rate and the additional momentum algorithm BP neural network. Firstly, tolerance analog circuit is simulated by OrCAD / ...
متن کاملAnalog Circuit Fault Diagnosis Based on Distributed Neural Network
In order to solve the problems caused by large dataset, such as the network scale and the training time, a new method of analog circuit fault diagnosis based on distributed neural network is presented in this paper. The model of distributed neural network is simply introduced. The arithmetic mechanism is depicted in detail and the arithmetic description is given. Simulation results show that th...

متن کاملKalman 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 ...
متن کاملResearch on k-fault diagnosis and testability in analog circuit
Fault diagnosis is very important for development and maintenance of safe and reliable electronic circuits and systems. Many k-fault diagnosis methods were put forward such as branch method, node method, loop method, mesh method, cut set method. But the tolerance effect as well as non-linear problems exist and are difficult to deal with. A fault diagnosis method for analog circuit is proposed i...
