Abstract
This paper presents an integrated sub-1V low power millimeter-wave CMOS voltage-controlled-oscillator (VCO). The VCO was fabricated with the commercial 1P6M 0.18μm CMOS technology. To reduce the power consumption, the self-body-bias scheme was used in the VCO design. Operated at 0.7V, the VCO circuitry consumes 2.1mW of power. The total chip size is 0.83mm × 0.35mm. The VCO tuning range covers from 52.2 GHz to 52.8 GHz and the corresponding Kvco is 860 MHz/V. The measured phase noise at 1-MHz offset from 52.2 GHz is -95 dBc/Hz, which leads to an excellent Figure-of-Merit (FOM) of -186 dBc/Hz.
