Innovative techniques for device large-signal noise simulations

摘要

Noise simulation of devices in RF and microwave applications requires to estimate the time-periodic noiseless working point, which in turn calls for the inclusion in the model of the circuit elements surrounding the device itself. In this contribution we present a 2D numerical noise model based on the drift-diffusion approximation able to tackle this issue, wherein both frequency- and time-domain methods are implemented: we discuss both of them, pointing out the main advantages of each approach.
