Abstract :
This paper presents a novel quadrature VCO (QVCO) implemented in a 47GHz SiGe technology. The QVCO is a serially coupled LC VCO that utilizes SiGe HBTs for oscillation and MOSFETs for coupling. The SiGe BiCMOS QVCO prototype achieves about 14.6 % tuning range from 4.3 to 5 GHz. The phase noise of the QVCO is measured as -115dBc/Hz @ 2MHz offset. The 5GHz QVCO core consumes 6mA current under 3.3V power supply and occupies 0.88mm2 area
