Abstract:Millimeter-wave/terahertz rotational spectroscopy offers ultra-wide-detection range of gas molecules for chemical and biomedical sensing. Therefore, wideband, energy-efficient, and fast-scanning CMOS spectrometers are in demand. Spectrometers using narrow-pulse sources and electromagnetic scattering [1] are broadband, but their resolutions do not meet the requirement (<;10kHz) of the absolute specificity. Alternatively, a scheme using a single tunable tone exhibits significant trade-off between bandwidth and performance. The 245GHz spectrometer in [2] presents 4mW radiated power.
