Abstract
This paper presents a rigorous phase noise analysis in
the /49
/102/50region for the differential CMOSLC-tank oscillator with
both nMOS and pMOS switch pairs. A compact, closed-form phase
noise equation is obtained, accounting for the noise contributions
from both tank losses and transistors currents, which allows a ro-
bust comparison between LC oscillators built with either one or
two switch pairs.
The fabricated oscillator prototype is tunable between 2.15 and
2.35 GHz, and shows a phase nois
