Abstract

A fully integrated 39.8-/43-GHz switchable VCO - for practical single-chip MUX/DEMUX LSIs in 0.18-μm SiGe BiCMOS technology - was developed. The VCO provides clock-signal for data rates of 39.8 and 43.0 Gbps. The VCO has a novel configuration of a half-frequency VCO and a frequency-doubler to realize a 7-GHz tuning range for tolerating process deviation and supporting dual mode. A sew temperature-compensation technique resulted in 0.6%-temperature-fluctuation of oscillation-frequency. Measured phase noise at a 1-MHz offset frequency was -85.0 dBc/Hz. Data transmission experiments between the MUX and DEMUX confirmed that this phase noise is allowable for use in 40-Gbps-class network systems.
