The talk begins with a revi ew of the fundamental and technological limiting factors to the spectral p urity of integrated RF oscillators\, and then proposes circuit solutions t o break the phase noise barrier in silicon technology. Phase noise can be scaled by resorting to the multi-core approach\, provided mismatches among multiple oscillators are carefully considered. As an example\, a 16-core (voltage-controlled) oscillator demonstrates -130dBc/Hz at 1MHz offset fro m 20 GHz minimum phase. A more elegant and efficient approach is then intr oduced. Leveraging the series resonance of a tank\, the remarkably lower r esistance rises considerably the tank active power\, thus enabling a remar kable improvement on the spectral purity. Two 10GHz BiCMOS VCOs exploiting the concept are proposed. The measured minimum phase noise is −138 dBc/ Hz at 1-MHz offset with 600mW from 1.2-V supply. Experimental results demo nstrate the lowest phase noise ever reported by fully integrated RF oscill ators in a silicon technology.\n\nAndrea Mazzanti (S’02–M’09–SM’ 13) received the Laurea and Ph.D. degrees in electrical engineering from t he University of Modena and Reggio Emilia\, Modena\, Italy\, in 2001 and 2 005\, respectively.
