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‐μm 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. © 2011 Wiley Periodicals, Inc. Microwave Opt Technol Lett, 2011; View this article online at wileyonlinelibrary.com. DOI 10.1002/mop.26192
