Abstract
Accurate clocks play a fundamental role in modern communication systems, especially given the trend towards ever increasing data rates. Atomic clocks easily achieve sub-ppb stability, orders of magnitude better than even the best quartz and MEMS-based references. Driven by recent developments in photonics and MEMS technology, they now dissipate several tens of mW and are matchbox size. The challenge is how to improve on this and realize clocks that can be used in mobile phones and tablets. This paper will present recent progress towards this goal with an emphasis on the required signal processing and RF circuitry.
