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...
