Abstract

Abstract — A mm-wave VCO tunable from 41 to 44.5 GHz (8% tuning range) is presented. It utilizes a differential tuning mechanism based on varactors and fixed MIM capacitors. Fabricated in a bulk CMOS 65nm technology, it consumes 3.6 mW and exhibits a phase noise of –106 dBc/Hz at 1 MHz offset from a 41.2 GHz carrier. The resulting FOM is –192.7 dBc/Hz, which is the best reported value for VCOs operating above 40 GHz. Twenty-nine samples are measured to analyze die-to-die variations of the VCO and results are presented.
