摘要：This paper presents a dual-loop chip-scale molecular clock (CSMC), which enhances the Allan Deviation performance by combining high signal-to-noise ratio of using fundamental mode and long-term stability of using higher order modes in derivative molecular absorption spectroscopy. In addition, digital frequency-error integration is adopted in the frequency-locked loop to provide an infinite open-loop DC gain, which fully suppresses any frequency drift caused by the temperature-sensitive crystal oscillator. This new generation CSMC is implemented in 65-nm CMOS, and achieves 20 ppt (part-per-tril
