Two low-power mm-wave voltage controlled oscillators (VCOs) designed in a 28-nm fully-depleted silicon-on-insulator (FD-SOI) CMOS process are demonstrated, using a push-pull differential architecture. Measurement show that the first VCO has a 10.8% tuning rage centered at 30.3 GHz, and the second has a 8.9 % tuning range at 58.7 GHz. The 30 GHz VCO consumes 1.06 mW from a 1 V supply, and has a −119 dBc/Hz phase noise at 10 MHz offset, achieving a figure of merit of −188.4 dB. The 60 GHz VCO consumes 1.35 mW and has a −111.9 dBc/Hz phase noise at 10 MHz offset, achieving a figure of merit of −186.2 dB. Their active areas are 0.03 mm2and 0.096 mm2respectively. |
