Abstract

This paper reports a capacitive-coupling multi-LC-tank fully-differential VCO with wideband 1/f3 phase noise (PN) corner reduction. It features two separate single-turn inductors and a differential-mode 1D-tuning capacitor bank to realize high-quality-factor high-impedance resonances at the 1x-to-2x of the oscillation frequency. Prototyped in 65nm CMOS technology, the VCO occupies 0.082mm2 and measures a tuning range (TR) of 24.5 to 28.3GHz. The FOM is 189.4dBc/Hz and the TR-insensitive 1/f3 PN corner is 200±50kHz.
