Abstract

The paper presents a generalized Green’s function approach to the simulation of trap-assisted generationrecombination (GR) noise in RF devices. By exploiting a few noninteracting trap levels, the superposition of the corresponding (stationary) GR spectra is shown, in a simple yet significant case study, to reproduce a 1/f or 1/f-like behaviour over a prescribed frequency range. The same trap distribution is also exploited for large-signal, cyclostationary noise simulations in forced periodic conditions. In this case, frequency conversion effects are present, and the low-frequency noise is shown to be upconverted from baseband to the other noise sidebands. The frequency conversion effects are also investigated in the case of a junction diode.
