Advances in 6G communication changes how machines and humans interact. The blossom of new applications demands significantly higher data bandwidth while preserving the mobility and sustainability of electronic wireless communication systems. It also demands an integrable system that allows convenient interactions between communication units and signal processing units. A review of CMOS-based THz communication system solutions is presented, with a focus on novel systematic EM-circuit co-design philosophy. This review starts with a review of THz power generation, followed by the discussion of THz localization and THz beamforming for efficient high-throughput communication.

A review on Terahertz end-to-end systems with an emphasis on integrated approaches is presented. Four major catalogs of THz integrated systems, including THz communication systems, THz imaging systems, THz radars, and THz spectroscopy systems, are reviewed in this article. The performance of integrated systems is compared with non-integrated solutions, followed by a discussion on the trend in future research avenues and applications.

“…In the beam-training mode, we demonstrate unique frequency-to-angle mapping with wide field-of-view for fast frequency division based beam-training. The proposed beamtraining method do not need costly/bulky external constructs such as Rotman Lens [6] or Leaky-Wave Antenna [7]. In the data communication mode, we achieve a 60% increase in modulation bandwidth compared to prior art consuming 33% lower power.…”

“…Early implementations relied on delay lines in all antenna branches [3], but this approach suffers from limited delay ranges when implemented at RF which renders it insufficient to achieve frequency dispersive beam training as proposed in this work. Recent advancement in TTD arrays with baseband delay elements and large delay range-to-resolution ratios [4], [5] improved the scalability and thus enabled the realization of fast beam training schemes in large arrays without needing any bulky and costly external constructs (such as Rotman Lens [6] or Leaky Wave Antenna [7]). Lastly, it does not have wideband spatial effects (beamsquint) inherent to wideband phase-shift based arrays.…”

Spatial signal processors (SSP) for emerging millimeter-wave wireless networks are critically dependent on link discovery. To avoid loss in communication, mobile devices need to locate narrow directional beams with millisecond latency. In this work, we demonstrate a true-time-delay (TTD) array with digitally reconfigurable delay elements enabling both fast beam-training at the receiver with wideband data communications. In beam-training mode, large delay-bandwidth products are implemented to accelerate beam training using frequencydependent probing beams. In data communications mode, precise beam alignment is achieved to mitigate spatial effects during beam-forming for wideband signals. The 4-element switchedcapacitor based time-interleaved array uses a compact closedloop integrator for signal combining with the delay compensation implemented in the clock domain to achieve high precision and large delay range. Prototyped in TSMC 65nm CMOS, the TTD SSP successfully demonstrates unique frequency-to-angle mapping with 3.8ns maximum delay and 800MHz bandwidth in the beam-training mode. In the data communications mode, a ∼ 12dB uniform beamforming gain is achieved from 80MHz to 800MHz. The TTD SSP consumes 29mW at 1V supply achieving 122MB/s with 16-QAM at 9.8% EVM.
