N2 - A novel miniaturized tri-band complementary metal-oxide-semiconductor (CMOS) voltage-controlled oscillator (VCO) utilizing a three-mode reconfigurable inductor is proposed. The reconfigurable inductor consists of primary and secondary windings with a center loop connected to each winding center-tap to enable three-mode operation. By adjusting the diameter of each winding and loop, the equivalent inductance for each mode can be designed independently, resulting in a high degree of freedom for a tri-band VCO with minimal Q-factor degradation. The VCO implemented in a 28nm CMOS process shows frequency tuning ranges of 16.78-20.13GHz, 19.8-24.15GHz, and 33-41.13GHz for each mode with corresponding phase noise and tuning range figure-of-merit (FoMT) values of -190.1, -190.9, -194.6dBc/Hz. The fabricated chip consumes 12.72mW and occupies a core area of 0.043mm2.
