Abstract :
This paper presents the design and measurement of an integrated millimeter wave wideband voltage controlled oscillator (VCO). This VCO employs the on-chip transmission lines and hyper-abrupt junction varactors to form high Q resonator. The VCO RFIC was implemented in a 0.13um 200GHz ft SiGe hetero-junction bipolar transistor (HBT) BiCMOS technology. The VCO oscillation frequency is around 25GHz, targeting at the ultra wideband (UWB) and short range radar applications. The VCO phase noise was measured around -82.5dBc/Hz at 500 KHz frequency offset. It has a wide tuning range from 23.8GHz to 26.3GHz. The core of VCO circuit consumes 10mA current from a 2.2V power supply and occupies 0.56×0.205mm2 area.
