A Ku-band low-power low-phase-noise LC-VCO IC with a novel feedback circuit is presented in this paper. The novel feedback circuit controls a bias voltage to the VCO core circuit to reduce the dc power consumption and guarantees the robust start-up of the oscillation. The leakage current is utilized to drive the feedback circuit so that the dc power consumption in the feedback circuit is suppressed. The proposed Ku-band LC-VCO IC has exhibited a measured phase noise of –133.9 dBc/Hz, an FoM of –192.0 dBc/Hz, and an FoMT of –200.2 dBc/Hz under the maximum total power consumption of 2.98 mW.
