Abstract

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.
