Abstract :
An ultra-low-voltage LC-VCO IC has been demonstrated using 130nm CMOS technology. The LC-VCO IC includes a cross-coupled nMOSFET pair, a spiral inductor, MOS varactors and a buffer amplifier. The LC-VCO IC is designed, fabricated and fully evaluated on wafer. The VCO IC exhibits a phase noise of -137 dBc/Hz at 1 MHz offset from the 2.2 GHz carrier at a supply voltage of only 0.5 V.
