Application of physical models to circuit simulations

摘要

In this contribution, we review the use of physical models for the noise simulation of devices operated in nonlinear conditions, thus requiring a full mixed-mode simulation of the device and of the embedding circuit. After presenting a detailed formulation of the model, we discuss two significant case studies: a downconversion GaAs MESFET mixer, and a detailed analysis and physical interprettion of low-frequency noise upconversion in a pn junction.
