Parameters Extraction for Equivalent Circuit Model Based on Artificial Intelligence

In this paper, a novel parameter extraction method for equivalent circuit based on artificial intelligence (AI) technique is proposed. The Y-parameters calculated by UltraEM
^®
, which is a high efficient electromagnetic simulation tool, are used as training data to establish corresponding AI model. With this AI model, the parameters of the equivalent circuit can be efficiently obtained by optimization method. An example of a spiral inductor is given to demonstrate the extraction procedure and validate the results.
