Recent advance in silicon on sapphire technology (SOS) is quite significant, and several applications of SOS devices have been already practically realized as a 1024 bit CMOS/SOS random access memory, a programmable logic array, a nonvolatile memory etc. The primary difficulties of the SOS structure, such as obtaining the epitaxial silicon films with acceptable electrical characteristics and with reasonably good crystal perfection, seem to be solved from the practical point of view for fabrication of MOS transistors on SOS wafer. Basic superiority of. the SOS structure compared with the bulk silicon structure has been confirmed through the high density CMOS LSI without any parasitic bipolar transistor effects between n-channel and p-channel transistors, and n-channel MOS LSI with higher speed due to decrease in parasitic capacitance of interconnections of both diffused layers and aluminum and/or polycrystal silicon layers. However, there still remain a number of phenomena which should be revealed prior to development of more advanced version of SOS LSIs. This paper will review the present state of the art, and discuss feasibility of SOS technology, looking at the following matters of interest.

A compact and wideband antenna array operating in the $\mathbf{C}, \mathbf{X}$ & $\mathbf{K u}$ bands is presented here. A planar array of eight identical wideband radiating elements is realized and then it is tested with the help of a $1: 8$ wideband power combiner. The performance of the complete passive network is tested after integrating it with the transmit-receive module. Additionally, the phase shifters were used with the transceiver module to switch the main beam of the array from - 10 to 10 degrees. The proposed solution is planar compact and has a stable radiation pattern over the entire operating frequency range.

With the increasing pollution of endocrine disruptors (EDCs) to water and the development of optical fiber sensing technology, it is necessary to develop new biosensors with simplicity, sensitivity and high specificity. Herein, we demonstrated an EDCs detection device based on graphene oxide (GO) functionalized S optical fiber taper (SFT) and biotin-SA signal amplification system for the detection of E2 concentrations in water samples. In this study, the sensing element was based on compact SFT that was obtained by fusing optical fiber through a fusion splicer. The immunosensor probe was constructed by functionalizing the SFT with GO using self-assembled technique, further coupling with streptavidin and specific biotinylated monoclonal antibody against E2. The mechanism of detecting E2 relies on measuring the external refractive index changes of STF induced by the target adsorption of analyte onto the antibody. In addition, we also prepared an optical fiber immunosensor without amplification signal system as a control. By experiment, we gained an optical fiber immunosensor with a high sensitivity value of 38.3 nm/(ng/mL) that was about 1.5 times better than that of the control immunosensor produced, which was due to the signal amplification, high biotin affinity and strong specificity of SA. The detection limit of (LOD) the immunosensor for E2 was 0.01ng/mL (S/N= 3). The results revealed that the developed optical fiber immunosensor was successfully applied to the fast, online, low cost and sensitive detection of E2 in environmental samples, and its detection effect is better than the control optical fiber immunosensor.

FLEXIBLE AND PRINTED ELECTRONICS 2020年第4期5卷 042001-042001页

Harnessing Laser-induced graphene (LIG) on various substrates, its optimization and application for various electronic devices has increased in the recent years. LIG has been reported as an alternative process for the realization of graphene for flexible electronics with excellent strength, conductivity and mechanical robustness. However, in a single-step manufacturing process, the development of a cost-effective, scalable electronic system using LIG is very challenging. In this work, a novel, simple, low-cost, and solid-state approach has been introduced to print and develop LIG-based conductivity traces and patterns. Here, the LIG conductive zones have been formed on various platforms by using phenolic resin (PR). The LIG regions were effectively developed from direct CO(2)laser ablation on the PR and polyvinyl alcohol (PR-PVA) composite sheets. This technique makes it possible to easily create highly conductive arrays on various substrates for realizing the components and devices for flexible electronics. By utilizing the augmented power and the speed of CO(2)laser, and the ratio of PR-PVA, the optimal conductivity of the formed LIG on PR-PVA sheet has been observed. Unique characteristics of LIG on PR-PVA include simple synthesis process, flexibility, ability to form a thin film with desired conductivity, and cost-effectiveness. The feasibility and viability of the successful LIG on PR-PVA sheet was demonstrated for applications like the capacitive touch sensor and the pressure sensor matrix.

The event-based vision sensor (EVS) is a new image sensor that detects the change in light intensity instead of the value of light. The mechanism of EVS has many advantages such as higher dynamic range, higher detection speed, and lower data redundancy. However, traditional EVSs use pre-defined contrast threshold voltage to detect events, which is risky because of the influence of process voltage temperature (PVT) fluctuation and array mismatch. To solve this problem, this paper presents a global threshold voltage finder technology for the EVS readout circuit. The binary search technology is used to acquire the flip voltage of comparators in the EVS pixel array. The simulation results show that the voltage error between the threshold finder result and the average of the pixel array is 3.83 mV. Compared with a single reference pixel finder, the voltage error reduces by 61% to the standard deviation of pixel arrays.

Domain-specific accelerators have become a key component in today's systems-on-chip (SoCs) and systems-on-package (SoPs), driving active research and product development to build novel accelerators for emerging applications such as machine learning, robotics, cryptography, and many more. This tutorial will discuss challenges and opportunities for the next generation of domain-specific accelerators, with a special focus on system-level implications of designing, integrating, and scheduling of future heterogeneous platforms. Specifically, we will cover: hardware optimization for efficient accelerator design; state-of-the-art SoC integration protocols (AXI, TileLink, CXL); and runtime system design to dynamically manage accelerator and shared resources at the system level.

solid state tritium detector for biomedical applications

Solid state tritium detector for biomedical applications

IEEE Symposium on Nuclear Science (NSS/MIC)

作者： J.S. Gordon R. Farrell K. Daley C. Oakes Radiation Monitoring Devices Inc. Watertown MA USA

Radioactive labeling of proteins is a very important technique used in biomedical research to identify, isolate, and investigate the expression and properties of proteins in biological systems. In such procedures, the preferred radiolabel is often tritium. Presently, binding assays involving tritium are carried out using inconvenient and expensive techniques which rely on the use of scintillation fluid counting systems. This traditional method involves both time-consuming laboratory protocols and the generation of substantial quantities of radioactive and chemical waste. The authors have developed a novel technology to measure the tritium content of biological specimens that does not rely on scintillation fluids. The tritiated samples can be positioned directly under a large area, monolithic array of specially prepared avalanche photodiodes which record the tritium activity distribution at each point within the field of view of the array. The 1 mm/sup 2/ sensing elements exhibit an intrinsic tritium beta detection efficiency of 27% with high gain uniformity and very low cross talk.< >
