With the increasing number of users and emerging new applications, the demand for mobile data traffic is growing rapidly. The limited spectrum resources of the traditional microwave and millimeter-wave frequency bands can no longer support the future wireless communication systems with higher system capacity and data throughput. The terahertz(THz) frequency bands have abundant spectrum resources, which can provide sufficient bandwidth to expand channel capacity and increase transmission data rate. In addition, with the rapid development of silicon-based semiconductor technology,its characteristic size keeps decreasing, and the radio frequency performance of active devices is gradually approaching the performance of III-V semiconductor technology. The realization of THz communication systems based on low-cost, high-stability, and easy-to-integrate silicon-based process has become a feasible solution. This review summarizes the reported silicon-based THz communication systems, as well as the key sub-circuit chips in these systems, including the local oscillator, power amplifier, low noise amplifier, on-chip antenna and transceiver chip, etc.

A 4th-order subharmonic downconversion mixer with a radio frequency (RF) of 480 GHz and intermediate frequency (IF) of 20 GHz that employs MOS symmetric varactors (SVARs) is demonstrated in 65-nm CMOS. The mixer achieves the minimum conversion loss of 25 dB at 20 GHz, VG = 0.5 V and VNW = 1 V. The return loss of the output port can reach nearly 30 dB, achieving a good matching effect, and can operate at a LO power of 9 dBm. The 4-GHz IF bandwidth spans between 18 and 22 GHz. © 2023 IEEE.

In this paper, an ultra-wideband 6-bit digitally controlled attenuator MMIC for the active phased array that integrates positive voltage digital driving circuits was developed, utilizing GaAs enhanced and depletion mode p-HEMT process. The attenuator design operates in an ultra-wide bandwidth of 2-18 GHz, with a dynamic attenuation range of 0.5-31.5 dB and an attenuation accuracy of less than 0.9 dB over the entire frequency band. The integrated DCFL (direct coupling field effect transistor logic) inverter circuit on the chip enables direct control of the attenuator with a positive voltage while occupying a chip area of only 2.7 mm2. © 2023 IEEE.

In this paper, an aging small-signal S-parameters modeling method for microwave transistors is explored using a genetic algorithm (GA) to optimize the Extreme Learning Machine (ELM) neural network. A dual GA-ELM neural network architecture was used to simulate the fresh S-parameters of InP heterojunction bipolar transistor (HBT) devices and the degradation of S-parameters after accelerated aging, respectively. Good agreement was achieved between measured and predicted results of the fresh and aging S-parameters within a frequency range of 0.1 to 40 GHz. © 2023 IEEE.

As a front-end signal processor in the receiver, the low noise amplifier has a crucial impact on the performance of the entire signal link. In this paper, a 40-67GHz broadband low noise amplifier MMIC is designed by 0.1μm InP HEMT process. The measured results show that the gain of the MMIC achieves 27dB with a gain flatness less than ±1dB in the full band. Both the input and output return losses are better than 10dB. At the same time, the typical value of the output 1dB compression point Po(1dB) is 0.5dBm and the representative noise figure is 2.2dB. The MMIC area is 2.4mm∗1.1mm. Good performance can be achieved in the target frequency band. © 2023 IEEE.

A precise integration of the optoelectronic device onto a functional platform, such as silicon photonics, LiNbO3 photonics or Si CMOS, is the key approach that makes the union of the different parts. Here, we propose a micro transfer-printer (μ-TPer) designing for high-accuracy optoelectronic and photonic integration. The used μ-TPer equips a multi-axis movement stage and visual-recognizing system, which recognizes the alignment marks and operates the aligning actions precisely. To employ this μ-TPer, a basic photonic integrated circuit of InP PD onto silicon microring resonator are realized, where the misalignment less than 1 μm can be obtained optimally. This equipment enables a powerful manufacturing route for the various optoelectronic and photonic integrations. © 2022 IEEE.

This paper presents a blind calibration algorithm for a multi-channel time-interleaved analog-to-digital conversion system implemented in MATLAB/simulink. The behavior level simulation of the calibration system is carried out. The simulation results show that the signal-to-noise ratio (SNR), signal-to-noise-distortion ratio(SNDR), and spurious-free dynamic range (SFDR) of the signal corrected by the calibration system are greatly improved, which lays a solid foundation for the subsequent digital circuit design. Behavioral simulations are presented for a 4-channel 10-bit TI-ADC in order to verify the effectiveness of the proposed method. Using the introduced calibration technique, SFDR increased by 33 dB on average. © 2023 IEEE.

This paper demonstrates the designed process and experimental performance of a W -band low-noise amplifier (LNA) MMIC based on a 0.1 mu m gate length GaN-on-SiC process. A considerable available gain can be realized at low voltage in W-band. At the same time, the desired LNA takes into account enhanced output power, large power capacitance, high withstand voltage, anti-static electricity and improved reliability of GaN technology, which is more convenient to integrate with other GaN power amplifiers and switches. The LNA is composed of a 3-stage common-source amplifier constructed to operate over an 88100 GHz frequency band. This measured amplifier achieves gain of 20-21dB, noise figure of 3.0-3.5dB, output power of 14.5dBm at 1dB compression point (P-1), power capacitance of 4 W, withstand voltage of 45 V and anti-static electricity of 2000 V. The MMIC is 3.1 mathrm{x}1.5 text{mm}{2} in size and consumes 0.4 W of dc power from a 5 V supply. © 2022 IEEE.

A Doherty Power Amplifier (PA) with high efficiency and high linearity that can be used in smart communication devices such as mobile phones in the sub-6GHz frequency band is proposed. This Doherty PA uses the InGaP/GaAs hetero-junction bipolar transistor (HBT) process. Compared with the traditional Doherty PA, the PA in this paper combines the choke inductance of the output collector and the phase compensation circuit with the output circuit of the Doherty PA respectively, which reduces the number of components required for matching. From the simulation, when the power supply voltage of the Doherty power amplifier is 4.2V, the operating frequency is 3.5GHz and the output power is 26.5dBm, the power added efficiency (PAE) reaches 34.5%, at the same time when using a 10MHz bandwidth LTE-3GPPFDD modulated signal the Adjacent Channel Power Ratio (ACPR) below to -35dBc. © 2023 IEEE.
