Abstract
An electronic device includes a package substrate, a circuit assembly, and a housing. The circuit assembly is mounted on the package substrate. The circuit assembly includes a first sealed cavity formed in a device substrate. The housing is mounted on the package substrate to form a second sealed cavity about the circuit assembly.
Claims14
A clock generator, comprising:
- a substrate having a first sealed cavity, the first sealed cavity containing dipolar molecules;
- clock generation circuitry coupled to the substrate, the clock generation circuitry configured to drive a signal into the first sealed cavity and, responsive to the driven signal, generate a clock signal at a frequency of quantum rotational state transition of the dipolar molecules;
- and
- a housing having a second sealed cavity, the second sealed cavity enclosing the substrate and the clock generation circuitry.
