This article presents a differential cross-coupled complementary Colpitts CMOS voltage-controlled oscillator (VCO). The low phase noise CMOS VCO has been implemented with the TSMC 0.35-mu m 2P4M CMOS technology and adopts a pair of cross-coupled PMOS transistors to achieve faster start-up oscillation. The VCO operates from 6.16 to 6.5 GHz with 5.3% tuning range. The measured phase noise at 1 MHz offset is -121.12 dBc/Hz at 6.417 GHz. The power consumption of the VCO core is 6.16 mW. The figure of merit is -189.37 dBc/Hz.
