For the non-stop demands for a better and smarter society, the number of electronic devices keeps increasing exponentially; and the computation power, communication data rate, smart sensing capability and intelligence are always not enough. Hardware supports software, while the integrated circuit (IC) is the core of hardware. In this long review paper, we summarize and discuss recent trending IC design directions and challenges, and try to give the readers big/cool pictures on each selected small/hot topics. We divide the trends into the following six categories, namely, 1) machine learning and artificial intelligence (AI) chips, 2) communication ICs, 3) data converters, 4) power converters, 5) imagers and range sensors, 6) emerging directions. Hope you find this paper useful for your future research and works.

In this article, we propose and demonstrate a spectrum-to-space mapping principle for localizing multiple wireless nodes in a simultaneous and single-shot fashion at terahertz (THz) frequencies. Spectrum-to-space mapping is achieved through two dual-port chip integrated waveguide (CIW)-based leaky-wave antennas (LWAs). Interfacing with the two LWAs, we integrate two transmitting and receiving chains operating between 360-and 400-GHz range in a single chip realized in a 65-nm bulk CMOS process. Utilizing the carefully engineered dispersive nature of the LWA and its frequency-dependent radiation patterns, we create unique spectrum-to-space calibration maps for both 1-D and 2-D angular localizations. The measured one-shot localization error variance is less than 1 • in 1-D space with 200-Hz-resolution bandwidth (BW) and less than 2 • in 2-D space for a 20-Hz-resolution BW. The high-resolution nature of the localization principle in a single-shot fashion makes this approach attractive for multi-wireless node localization, link discovery, beam-forming, beam-management, and beamoptimization methods.

“…Most works on analog beamforming networks favor phase quantization, as it can be implemented with simple phase shifters [19], [20]. Quadrature quantization, however, has higher expressivity, enabling control of the amplitude as well as of the phase, and is also practically viable [21], [22]. Both alphabets are fully specified by their alphabet cardinality (AC): their scale is arbitrary as it can be absorbed into β; see ( 4) and (9).…”

tl;dr-Low-resolution analog-to-digital converters (ADCs) simplify the design of millimeter-wave (mmWave) massive multi-user multiple-input multiple-output (MU-MIMO) basestations, but increase vulnerability to jamming attacks. As a remedy, we propose HERMIT (short for Hybrid jammER MITigation), a method that combines a hardware-friendly adaptive analog transform with a corresponding digital equalizer: The analog transform removes most of the jammer's energy prior to data conversion; the digital equalizer suppresses jammer residues while detecting the legitimate transmit data. We provide theoretical results that establish the optimal analog transform as a function of the user equipments' and the jammer's channels. Using simulations with mmWave channel models, we demonstrate the superiority of HERMIT compared both to purely digital jammer mitigation as well as to a recent hybrid method that mitigates jammer interference with a nonadaptive analog transform.
