A 328 /spl mu/W 5 GHz voltage-controlled oscillator in 90 nm CMOS with high-quality thin-film post-processed inductor

A novel low-power 90 nm CMOS 5.8 GHz voltage-controlled oscillator, using a high quality thin-film post-processed inductor, is presented. This 5.8 GHz VCO has a power consumption of 328 /spl mu/W with a supply voltage of 0.82 V, and a phase noise of -115 dBc/Hz at 1 MHz offset over a 148 MHz tuning range. To the authors' knowledge, this VCO is the lowest power dissipated 5 GHz CMOS VCO reported.
