Abstract
This paper presents a low-noise Colpitts VCO with transformer-based resonator and a 20-to-40GHz frequency doubler for use in 76~77GHz long-range radar and 77~81GHz short-range radar transceivers. To reduce supply pushing and AM-to-PM noise conversion in the high-gain VCO, a differentially tuned, transformer-coupled varactor is used. Implemented in 0.12-μm SiGe BiCMOS technology, the VCO and doubler achieve an 11% continuous tuning range from 37.5-42GHz, and a phase noise between -103 and -106dBc/Hz at 1MHz offset from the 40GHz carrier.Keywords
