Abstract :
This letter introduces a new method for steady state analysis of nonlinear circuits with frequency dependent parameter components. The method enables treatment of distributed parameter components in a wavelet domain steady state circuit simulator. The method features thresholding of the convolution matrix in wavelet domain in order to reduce computational cost and is suitable for highly nonlinear circuits with distributed parameters under multitone excitations.
