Abstract:In this article, a distributed-swing-boosting and harmonic-impedance-expanding multi-core oscillator is proposed to achieve low phase noise and high figure-of-merit (FoM), simultaneously. First, a distributed-coupling multi-core topology is introduced to reduce the chip area with no mode ambiguity. Then, the distributed-swing-boosting and harmonic-impedanceexpanding structure is developed to boost the gate swing and square-like waveform of V DS . The common-mode (CM) resonances around the second harmonic and t… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
