Abstract

A fully integrated 10-GHz-band voltage-controlled oscillator (VCO) has been designed and fabricated using commercial 0.18-μm CMOS technology. The complementary cross-coupled differential topology is adopted in the design. The measured phase-noise is around -89 dBc/Hz at the offset frequency of 100 kHz from the center frequency of 9.83 GHz, the output frequency tuning range of the fabricated VCO is 1.1 GHz ranging from 9.3 to 10.4 GHz, and the power consumption of the core VCO circuit is 5.8 mW. The design is the first one that adopts the complementary cross-coupled circuit structure for 10-GHz-band oscillators, and whose performances of the VCO are the best ones for 10-GHz-band oscillators, compared with the 10-GHz-band CMOS oscillators reported earlier.
