Abstract

This paper presents a low-phase-noise differential bipolar Colpitts VCO, implemented in a 0.35μm BiCMOS process. A time-variant phase noise analysis yields closed-form symbolic expressions for the dominant noise sources in the I/f2 phase-noise region. Measurements show a phase noise of -123 dBc/Hz at 1 MHz offset from a 2.8-3.1 GHz carrier, for a figure-of-merit of 183 dBc/Hz. A very good agreement between the derived theoretical formulas, spectreRF simulations, and measurements is observed.
