A 5 GHz‐band voltage‐controlled oscillator employing on‐chip coplanar‐waveguide resonator instead of inductor–capacitor–resonator is proposed, designed, and fabricated in 0.18 μm CMOS technology.The advantages of the proposed VCO are the wider frequency‐tuning range; smaller chip area and phase noise is to be −117 dBc/Hz (@1 MHz offset frequency), which is comparable to that of a conventional LC–VCO. © 2010 American Association of Anatomists Microwave Opt Technol Lett 52: 763–766, 2010; Published online in Wiley InterScience (www.interscience.wiley.com).
