Several negative-resistance cells in LC oscillators are also compared. The LC source-degenerated topology is demonstrated through a 114-GHz push-push fully integrated LC VCO implemented in TSMC 0.13-μm CMOS process. With core power consumption of 8.4 mW, the tuning range at the fundamental port is 56.4-57.6 GHz and at the push-push port is 112.8-115.2 GHz. The measured phase noise at the fundamental port is -113.6 dBc/Hz at 10-MHz offset. This VCO is believed to have the best figure of merit among MMW VCOs using bulk CMOS processes. © 2007 IEEE.CMOS; Millimeter-wave (MMW); Negative-resistance cell; Voltage-controlled oscillators (VCOs)[SDGs]SDG7journal article10.1109/JSSC.2007.8971362-s2.0-34249858060
