Nonlinear circuit simulation based on adaptive wavelet method

A novel numerical method, Fast Wavelet Collocation Method (FWCM), was first proposed to explore a new direction of circuit simulation. However, it has not been studied in detail how to effectively apply the FWCM to solving nonlinear systems. In this paper, we explore the iterative and adaptive schemes which extend the FWCM to the nonlinear systems. Numerical results are presented which match well with the SPICE simulation.
