Enhanced steady-state simulation of nonlinear integrated microelectronic devices and circuits

Abstract

With the rapid advancement of electronic and microelectronic technologies, it has become crucial to efficiently characterize and simulate semiconductor devices and systems under various operating conditions. These circuits are characterized by their nonlinear behavior that should be captured in order to efficiently integrate them in different types of automated simulations. Due to the increased complexity of traditional simulation methods, such as the Harmonic Balance approach, obtaining the system moments of such networks becomes essential and reduces the CPU cost of simulations. They allow us to perform Model Order Reduction (MOR), distortion analysis, and sensitivity analysis. This work presents a technique to obtain the system moments and steady-state solution of nonlinear circuits with different types of nonlinear behavior. Furthermore, a comparison between the Harmonic Balance simulation and moments method is performed to demonstrate the speed-up and efficiency of the presented work.
