The synchronous latch is combined with adding operation to improve the calculation speed. A single-level parallel-gated circuit is designed using majority decision algorithm to reduce the power consumption. Measurement results show that the maximum clock frequency of the full adder is 32.2-GHz, and the overall power consumption is 350mW.

Physical realization of electrical synapses with good reliability aroused great interest due to rapid development of neuromorphic computing. Meanwhile, a new family of two-dimensional transition metal carbides (TMC) has exhibited great potential in performance improvement of electronic devices. However, there are very few investigations for performing synaptic devices using transition metal carbides. Moreover, reliability is crucial for achieving good biological plasticity as well as a controllable synaptic system. In this work, synaptic devices with transition metal carbide were successfully fabricated and reliability has been studied in details. Resistance window of memristor has been able to achieve 7 orders, which provides a possible solution in building artificial neural networks with accurate and efficient learning capability.

A two-dimensional(2-D) analytical model for substrate effect of lateral power devices is developed. By solving the 2-D Poisson's equation, an analytical model is proposed and verified by the agreements between the analytical results and numerical simulation results using MEDICI. It suggests that the optimized substrate voltage modules the distributions of the surface potential and electrical field, whose effect is equivalent to changing the concentration of the drift region. As a result, the breakdown voltage is improved.

Neuromuscular junctions (NMJs) are specialized synapses that enable the efficient transduction of neural signals into muscle contractions in biological systems. Desirable artificial NMJs aim to replicate biological synaptic plasticity and high-power actuation for advanced robotics and prosthetics, but face challenges in achieving sufficient flexibility, strength, and self-contained operation. Here, we report a novel artificial NMJ based on a silicon carbide (SiC) ferroelectric field-effect transistor. By integrating a ferroelectric floating gate dielectric with a wide-bandgap SiC transistor, we achieve a wide range of non-volatile conductance modulation, enabling the emulation of long-term synaptic plasticities. We demonstrate the PZT-SiC transistor's higher threshold voltage and lower operating currents compared to traditional SiC transistors, resulting in reduced power consumption. The device exhibits excellent synaptic plasticity, with the ability to modulate synaptic weights through successive test cycles and upon pulsatile stimulation. We showcase the potential of the PZT-SiC synaptic transistor through its application in convolutional image processing, where it successfully extracts horizontal and vertical features using Sobel kernels. Our work presents a promising hardware platform for efficient and scalable artificial NMJs, paving the way for advanced biohybrid systems and neuromorphic robots. © 2024 IEEE.

A novel mass sensor based on the nanomechanical transistor is designed. Based on giving the dynamic structure model, the transfer equations of the coupled mechanical part and the charge part are listed. Their parameters are obtained through experiments, and the dynamic displacement, velocity, and charge shuttle are numerically analyzed. Furthermore, the relationship between current changes of a passive beam with sensed mass is studied, proving the sensor's capability in detecting a small mass. Ultimately, the simulation results show that in this way can we get a mass sensor with high-quality sensitivity. The sensor's working range is in the 10-21 kilogram(zg) range. © 2019 IEEE.

In this paper, a class of 3D bandpass frequency selective structures (FSSs) using stacked planar slotlines is proposed to exhibit bandpass filtering response of high performance. Firstly, a traditional slot-type frequency selective surface and the proposed stacked planar slotlines are introduced successively, and their operating principles are discussed to provide a comparison with each other. Then, two design examples on the basis of the stacked slotlines are presented to exhibit bandpass response with wide out-of-band rejection and high frequency selectivity, respectively. It is found that the stacked slotline structures can produce controllable multi-mode resonance and be exactly analyzed by using transmission-line theory over a wide frequency range. © 2018 IEICE

In this paper, we propose a half-mode substrate integrated waveguide (HMSIW) leaky wave antenna (LWA) based on composite right/left handed (CRLH) transimission line (TL). The unit cell of the proposed antenna consists of two vertical slots on the microstrip and two metal vias. The equivalent series capacitance and the equivalent shunt inductance in the CRLH structure are realized by vertical slots and two vias, respectively. We simulated the unit cell and the proposed antenna. The antenna can achieve continuously wide beam scanning from backward to forward. The beam scanning angles from -50 degrees to 30 degrees.
