Supercapacitor energy storage system is commonly composed of a large number of cells in parallel and series, which will increase the system's complexity and decrease its reliability and safety. In order to make sure that the system is in good condition during working cycles, mastering each cell's current performance is a key point. The current performance of supercapacitor can be described by some...
The intelligent fault diagnosis method based on neural network is one of the most practical diagnosis methods in nonlinear analog circuit, the selection of appropriate test excitation signal can improve the diagnosis accuracy. The paper studies fault diagnosis excitation optimization method based on simulated annealing and genetic hybrid algorithm. In nonlinear analog circuit fault diagnosis takes...
In this paper, a simple wideband circuit model for on-chip spiral inductors is presented. The model shows excellent agreement with measured data mostly within 4.91% across a variety of inductor geometries up to 20 GHz. The proposed model has been verified with measured results of inductors fabricated in 0.13 μm CMOS process. The inductors have two dimensions: turn and inner radius. The new model accurately...
