Abstract: Terahertz operation of Complementary Metal Oxide Semiconductor (CMOS) circuits and systems has become a reality. CMOS is the cost-effective IC technology used to manufacture the bulk of electronics including those for smartphones, tablets, personal computers and others. Use of CMOS IC technologies enables affordable implementation especially in high volume. Signal generation up to 1.33 THz, coherent detection up to 1.2 THz and incoherent detection up to ~10 THz have been demonstrated using CMOS integrated circuits. Furthermore, highly integrated transceivers operating at frequencies up to ~400 GHz have been demonstrated. In addition, the affordable approaches for packaging and testing terahertz CMOS circuits are emerging. The performances of these CMOS circuits are or close to being sufficient to support electronic smelling using rotational spectroscopy that can detect and quantify concentrations of a wide variety of gases including that of volatile organic compounds, and imaging that can support operation in a wide range of visually impaired conditions such as fog, rain, dust, smoke and fire. Considering how smell is used, the application opportunities should almost be limitless for electronic smelling. The terahertz CMOS circuits can also be used to image through packaging for condition monitoring of a variety of contents starting from manufacturing to sales and points of use. Terahertz imaging can also be used to monitor moisture levels of objects. This presentation describes the state of art for terahertz CMOS circuits and systems, and more importantly, describes demonstrations of electronic smelling and imaging using the circuits and systems to motivate discussions needed to identify potential AgriFood applications.
