Hence, some level of customization must be carried out by the IP provider in order to fulfill their customer needs. In this paper, we present a flexible ring oscillator IP designed for a 40nm CMOS ...

“The accuracy of an oscillator depends on how much holdover time you require. GNSS has a natural resolution of roughly 20 ns. At 5 ns, you start to rely on your local oscillator to do the next level ...

Correspondingly, a novel RFF feature, named cyclic similarity (cyc-similarity), is proposed to depict the oscillator drift. Simply combining the cyc-similarity feature with a K-nearest neighbor (KNN) ...
