Abstract :
This paper presents a comparison of 100 GHz Colpitts VCOs fabricated in two generations of SiGe BiCMOS technology, with MOS and HBT varactors and with integrated inductors. Based on a study of the optimal biasing conditions for minimum phase noise, it is shown that VCOs can be used to monitor the noise performance of the SiGe HBTs at mm-waves. Measurements and simulations show a 104 GHz VCO operating from 2.5 V with phase noise of -101.3 dBc/Hz at 1 MHz offset, which delivers +2.7 dBm of differential output power at 25degC, with operation up to 125degC
