A nonlinear HBT table-based model is presented in which low-frequency (LF) noise effects are incorporated, thus allowing for precise oscillator design. The model uses four table-based nonlinear functions: I(c), Q(c), V(be) and Q(b), and takes into account temperature and noise behaviour. This approach is able to predict the LF noise behaviour under both static and dynamic conditions by using cyclostationary noise sources. HBT-based oscillators have been designed using this model, and very good predictions have been obtained for the oscillation frequency, the output power and the phase noise.
