Crossover Ring Oscillator PUF

2017 18th International Symposium on Quality Electronic Design (ISQED), 2017
Ring Oscillator (RO) Physical Unclonable Function (PUF) is one of the most popular silicon PUFs which exploit manufacturing variations during the chip fabrication process. RO PUF can generate secret bits by comparing the frequency difference between two ROs.

Interconnected ring oscillators

Journal of Optics A: Pure and Applied Optics, 2000
Threshold and operation conditions of the interconnected photorefractive ring oscillators are investigated, using the grating action method. Three types of two connected oscillators are considered, the first one consisting of two transmission grating crystals, the second one of two reflection grating crystals, and the third one of one transmission and ...

The behavior of rings of coupled oscillators

Journal of Mathematical Biology, 1985
Coupled oscillators in a ring are studied using perturbation and numerical methods. Stability of waves with nearest neighbor weak coupling is shown for a class of simple oscillators. Linkens' model for colorectal activity is analyzed and several stable modes are found.

Photorefractive ring oscillators

Journal of the Optical Society of America B, 1995
We consider the theory of photorefractive ring oscillators, using our unified solution method. Both unidirectional and bidirectional ring resonators are analyzed, based on the two-wave mixing process with crossed polarization and the four-wave mixing process with parallel polarization in photorefractive crystals.

Statistical analysis for the oscillation frequency of a ring oscillator

2010 IEEE International Conference of Electron Devices and Solid-State Circuits (EDSSC), 2010
It is important to find the statistical characteristics of the ring oscillators in mass production but the computational complexity prevents us from finding the distribution of these characteristics. Consequently, predicting the statistical parameters of these characteristics is much more practical.

Jitter in Ring Oscillators

2009
Jitter in ring oscillaton is theoretically described, and predictions are experimentally verified. A design procedure is developed in the context of time domain measures or oscillator Jitter in a plase-locked loop (PLL). A major contribution is the identification of a design figure of merit k , which is independent or the number of stages in the ring.
