Large Signal Analysis of On-Chip Interconnects Using Transport Based Approach

摘要

A large signal analysis of on-chip interconnects is presented. A set of nonlinear equations combining the motion equations of charge carriers and Maxwell's equations is devised in the frequency domain for the fundamental mode and harmonics and then solved by the finite element method and Newton's iterations. This analysis provides knowledge on field-carrier interaction, substrate nonlinearity and loss, slow-wave effect, etc. Numerical examples are provided for some practical material and geometrical parameters.
