A new PMOS backgate quadrature voltage controlled oscillator (QVCO) is designed and implemented using TSMC 0.18 μm 1P6M CMOS technology.The phase noise of the PMOS back‐gate coupled QVCO operating at 1.5 V is measured to be −100 dBc/Hz and −125.08 dBc/Hz at 100 KHz and 1 MHz offset, respectively, for a low power consumption of 15 mW. The backgate QVCO demonstrates a wide frequency tuning range, a low phase noise, and a low power consumption. The corresponding figure‐of‐merit of the QVCO is −186 dBc/Hz. © 2010 Wiley Periodicals, Inc. Microwave Opt Technol Lett 52:2682–2685, 2010; View this article online at wileyonlinelibrary.com.
