A 3 mW 54 GHz 0.18 mu m BiCMOS voltage controlled oscillator with supply injection locking

摘要

The key considerations of low power injection-locked oscillator (ILO) are analyzed. Using a supply injection topology, the proposed ILO is able to work at lower supply voltage with a good balance of other performances. Fabricated in Tower JAZZ 0.18 m SiGe BiCMOS technology, a prototype of ILO with supply injection achieves an operating frequency ranges from 53.2 to 55.3 GHz with a minimum input power of -35 dBm for a fixed control voltage. Occupying a silicon area of 0.24 mm(2), the core circuit consumes 3 mW from a 0.7 V power supply. (c) 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1912-1914, 2015
