| Popis: | In this paper, we present the design methodology and measurement results of a low-power, ultra-wide range Voltage Controlled Oscillator (VCO), with frequency range varying from 13. 1-18.4GHz. The design is fabricated in the 22-nm fully depleted Silicon-on-Insulator (FDSOI) CMOS technology from Globalfoundaries. The VCO is interfaced with a cascode butter. The physical insights of the super-low-threshold-voltage transistors with adaptive back-gate-biasing is used in the design implementation. The fabricated chip is characterized on the wafer-probe station using manual and automated measurements. The VCO exhibits a frequency-tuning ratio (FTR) of 33.3 % and a power consumption of $\approx$4.5mW with a supply voltage of 500 mV and back gate bias voltage of 500 mV. |
