A 2-3 GHz CMOS inductance-capacitance (LC) voltage-controlled oscillator (VCO) integrated with high-Q micro-electromechanical systems (MEMS) Cu inductors is reported. While dissipating only 6.3 mW, a phase noise of -121 dBc/Hz at 600 kHz offset from 2.78 GHz carrier is achieved. This MEMS VCO has the largest power-frequency normalized figure-of-merit (12.5 dB) among the Si bipolar and CMOS LC VCOs.
