Abstract
This letter presents a novel bias-varied low-power K-band voltage controlled oscillator (VCO) in a standard 90 nm CMOS technology. This circuit exhibits low power consumption of 3mW and a 12.2% tuning range with low phase noise characteristic. These performances are realized by combination of the transformer-feedback and the switchable active circuit block, which can control the dc power at different frequencies and improve the phase noise.
