Abstract:Recent progress of on-chip spectroscopic systems enables a new set of highly-stable frequency references (i.e. clocks) with low cost, power and volume. It is based on the rotational spectrum of gaseous molecules in sub-THz regime, a physical mechanism alternative to that in traditional atomic clocks. This scheme also enables fast start-up operation and robustness against mechanical vibration and external electromagnetic fields. This paper demonstrates the first chip-scale molecular clock in 65nm CMOS which probes the 231.061GHz spectral line of Carbonyl Sulfide (16O12C32S). The clock consumes
