Abstract-The simulation of generation-recombination (GR) noise under periodic large-signal conditions in a partial differential equation-based silicon device simulator is presented. Using the impedance-field method with cyclostationary noise sources, it is possible to simulate the self-and cross-spectral densities between sidebands of a periodic large-signal stimulus. Such information is needed to develop noise correlation matrices for use with a circuit simulator. Examples are provided which demonstrate known results for shot noise in bipolar junction transistors. Additional results demonstrate the upconversion of low-frequency GR noise for microscopically cyclostationary noise sources and provide evidence for applying the modulated stationary noise model for low-frequency noise when there is a nearly quadratic current dependence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
