- •
Given their usefulness as RNG’s and PLL’s, RO’s are building blocks of digital circuits.
- •
Jitter is unavoidable in RO’s and consequently it needs to be characterized.
- •
Jitter measures using Information Theory quantifiers (ITQ) are proposed.
- •
Two of these ITQ’s are robust and may be implemented experimentally.
- •
We encountered that a dual entropy plane allows a visual comparison of results.
