NDLI: Reviews of leeson model of oscillator phase noise

Content Provider	IET Digital Library

Abstract	Through theoretical deduction, two new explanations of Leeson model are presented: the corner frequency of high Q oscillators in the phase noise curve should be the frequency at the intersection of the f 0 curve segment after adding 3 dB and the f −1 curve segment; f 0 /2Q L of low Q oscillators in the phase noise curve should also be the frequency at the intersection of the f 0 curve segment after adding 3 dB and the f − 2 curve segment. Moreover, these two new explanations were verified by the experimental data of a reported 80 MHz high Q quartz crystal oscillator and a reported low Q lithium tantalate (LiTaO3) oscillator, respectively. The results could help researchers and engineers properly estimate the key parameters of oscillator phase noise.
