Abstract :
In this paper, two fully integrated voltage-controlled oscillators (VCOs) in a 200-GHz fT SiGe bipolar technology are presented. The oscillators use on-chip transmission lines at the output for impedance transformation. One oscillator operates up to 98 GHz and achieves a phase noise of -85dBc/Hz at an offset frequency of 1 MHz. It can be tuned from 95.2 to 98.4 GHz and it consumes 12 mA from a single -5-V supply. The second oscillator operates from 80.5 GHz up to 84.8 GHz with a phase noise of -87dBc/Hz at 1-MHz offset frequency. The output power of both circuits is about -6dBm.
