Abstract
A molecular clock which utilizes a rotational spectrum of gaseous molecules in a sub-THz region for clock stabilization is described. The molecular clock has a fast start-up characteristic and is also robust against mechanical vibration or variation of electromagnetic field. Also described is a chip-scale implementation of a molecular clock. In an embodiment, a molecular clock chipset only consumes a DC power of 66 mW. While providing a highly stable, compact and energy efficient time generator of portable devices.
