Abstract	An enhanced swing differential Colpitts VCO (ESDC-VCO) dramatically improves the swing of a Colpitts VCO by allowing the signal to swing below ground and above the supply voltage. Fabricated in a 1P8M 0.13 um CMOS process, the ESDC-VCO operates at 4.9GHz with a 0.475-V supply and consumes 2.7mW. The measured phase noise is -136.2 dBc/Hz at a 3-MHz frequency offset. The ESDC-VCO employs digital amplitude control and achieves a Figure of merit (FOM) of 196.2 dBc/Hz, making it the highest performing integrated LC oscillator to date.
