Abstract
A fully integrated low phase-noise and wide tuning-range differential Colpitts voltage-controlled-oscillator (VCO) designed and fabricated in 0.13um SiGe BiCMOS technology at 28 GHz for 5G wireless communications is presented. The proposed VCO utilizes inductive emitter degeneration and resistive tail bias to achieve low phase noise and wide tuning range. The measured phase noise is about −109.1 dBc/Hz at 1 MHz offset at a center frequency of 27.6 GHz and the measured tuning range is from 25.1 GHz to 29.9 GHz (17.3%). The measured output power delivered by the VCO is +6.5 dBm. Both the phase noise and the tuning range of this work are comparable with other silicon-based VCOs around 28 GHz.
