  • Abstract
    A modified K-band differential Colpitts voltage-controlled oscillator (VCO) which uses gm-boosting and capacitive filtering techniques to improve the performance of phase noise is proposed. The VCO achieves a good phase noise of-108.19 dBc/Hz at 1-MHz offset frequency, and the chip size is merely 0.27 mm2. The dc power consumption is 32 mW from a 2.2-V power supply. Compared with the previously published K-band VCOs, the proposed Colpitts VCO exhibits a superior phase noise characteristic and a highest FOM.
