Experimental set-ups are presented to achieve the choice of a transistor to be used in low noise oscillators and to study the correlation between phase noise and low frequency noise. Modelling guidelines are then described to help in the understanding of the noise conversion process. Simple rules of noise reduction are derived from simplified small signal models but the emphasis is put on more complete modelling approaches. These accurate models are affected by yet unsolved (or partially unsolved) problems such as : the influence of the large signal behaviour on the noise sources or the physically unacceptable cancellation of the phase noise in special biasing conditions.
