Embedded System Design for Miniature CPT Atomic Clock Circuit

Abstract

We present our developed embedded system based coherent population trapping (CPT) atomic clock circuit designed for the Miniature Atomic Clock. The size of the circuit is 30mm × 30mm, and the power consumption is 130mW. We connect this circuit to a physics package to form a CPT atomic clock with short-term frequency stability of 4 × 10-11τ-1/2.
