Abstract :
A low-phase-noise and low-cost millimeter-wave voltage-controlled oscillator (VCO) has been fully integrated in commercial SiGe bipolar technologies. By varying the bias voltage of the on-chip varactor, the frequency can be continuously tuned from 43.6 to 47.3 GHz. In this frequency range, single-sideband phase noise between -103 and -108.5 dBc/Hz at 1 MHz offset frequency was measured. The output voltage swing of the differential circuit is about 0.85 V/sub p-p/ for the single-ended and 1.7 V/sub p-p/ for the differential output.
