AbstractA millimeter-wave current-reuse voltage-controlled oscillator (VCO) features a single-turn multi-tap inductor and two separate differential-only switched-capacitor arrays to improve the power efficiency and phase noise (PN). Specifically, a single-branch complementary VCO topology, in conjunction with a multi-resonant Resistor-Inductor-Capacitor-Mutual inductance (RLCM) tank, allows sharing the bias current and reshaping the impulse-sensitivity-function. The latter is based on an area-efficient RLCM tank to concurrently generate two high quality-factor differential-mode resonances at the fundamental and 2nd-harmonic oscillation frequencies. Fabricated in 65-nm CMOS technology, our VCO at 27.7 GHz shows a PN of-109.91-dBc/Hz at 1-MHz offset (after on-chip divider-by-2), while consuming just 3.3 mW at a 1.1-V supply. It corresponds to a Figure-of-Merit (FOM) of 187.6 dBc/Hz. The frequency tuning range is 15.3% (25.2 to 29.4 GHz) and the core area is 0.116 mm2.
