CMOS (Complementary Metal Oxide Silicon) integrated circuits (IC's) technology is emerging as a means for realization of capable and affordable systems that operate at frequencies near 300GHz and higher. This is lowering a key barrier for utilizing the sub-millimeter electromagnetic waves in everyday applications. Despite the fact that the unity maximum available gain frequency, f max of NMOS transistors (with connections to the tope metal layer) has peaked at ~320 GHz, 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 rotational spectroscopy transceivers operating at frequencies up to near 300 GHz, 300-GHz and 400-GHz concurrent transceiver pixels and arrays for high resolution radar imaging, and 300-GHz and 390-GHz transmitters, and 300-GHz receivers for high data-rate communication have been demonstrated in CMOS. The performances of these CMOS circuits are sufficient or close to being sufficient to support electronic smelling using rotational spectroscopy that can detect and quantify concentrations of a wide variety of gases; imaging that can enable operation in a wide range of visually impaired conditions; and high-bandwidth communication. Lastly, techniques for affordable packaging and testing sub-millimeter wave systems are suggested based on experimental demonstrations.

This paper presents challenges and design perspectives for terahertz (THz) integrated circuits and systems. THz means different things to different people. From International Telecommunication Union (ITU) perspective, THz radiation primarily means frequency range from 300 − 3000 GHz. However, recently, a more expansive definition of THz has emerged that covers frequencies from 100 GHz to 10 THz, which includes sub-THz (100 − 300 GHz), ITU-defined THz frequencies. This definition is now commonly used by communication theorists, and since this paper is intended for people with a wide variety of expertise in system and circuit design, we have adopted the latter definition. The paper brings to the open unmitigated shortcomings of conventional transceiver architectures for multi gigabit-per-second wireless applications, unfolds challenges in designing THz transceivers, and provides pathways to address these impediments. Furthermore, it goes through design challenges and candidate solutions for key circuit blocks of a transceiver including front-end amplifiers, local oscillator (LO) circuit and LO distribution network, and antennas intended for frequencies above 100 GHz.
