    Abstract: In this article, a 24-GHz VCO composed of a 12-GHz
    VCO and an active frequency doubler is presented. This work is implemented
    by using the 0.18-m 1P6M CMOS process. The VCO and active
    frequency doubler with a 1.5 V supply consume 30 mA. The phase
    noise of measurement is 107.5 dBc/Hz and 123.1 dBc/Hz at 1-MHz
    and 10-MHz offset, respectively. A tuning range of 2.3 GHz is achieved
    by using varactor. The measurement shows a good efficiency of translation
    of frequency doubler and the oscillator has a good figure of merit
    (FOM) of 180 dBc/Hz. © 2009 Wiley Periodicals, Inc. Microwave Opt
