A 6.3–7.6 GHz VCO Achieving 192.7 dBc/Hz FoM With Dual Common-Mode Resonances
This letter presents a complementary voltage-controlled oscillator (VCO) featuring dual common-mode (CM) resonances. A triple-coupled transformer is leveraged to attain both the second and fourth harmonic resonances at the head and tail common sources of the complementary VCO, significantly suppressing the noise upconversion to the tank. Implemented in a 65-nm CMOS process, the prototyped VCO achieves a frequency tuning range from 6.3 to 7.6 GHz, a phase noise of −116.1 dBc/Hz at 1-MHz offset, and a figure-of-merit (FoM) of 192.7 dBc/Hz with a power consumption of 1.2 mW.
