A time-variant analysis of fundamental 1/f3 phase noise in CMOS parallel LC-tank quadrature oscillators

Author

Summary, in English

This paper presents a rigorous time-variant analysis

of the 1/f MOS device noise upconversion into 1/f^3 phase noise

for two of the most popular parallel-coupled quadrature CMOS

harmonic oscillators. Simple closed-form equations for the fundamental

1/f^3 phase-noise spectrum are derived and validated

through SpectreRF simulations, proving that the two topologies

display remarkably different sensitivities to the low-frequency

noise sources. Based on the developed analysis, useful general

design insights are also presented.
