Dual-Core High-Swing Class-C VCO design

다국어 초록 (Multilingual Abstract)

We utilize the idea of reducing phase noise (PN) by combining multiple oscillators. The dual core LC-tank oscillator is based on a high-swing class-C topology and realized in 65-nm CMOS process. As a result of simulation, it is tunable within 1.12-1.25 GHz, while drawing 1.7 mA from a 1.2 V power supply. Phase noise and figure-of-merit (FOM) are −135.0 dBc/Hz and 194 dB at 1MHz, respectively, from a 1.12 GHz carrier frequency.
