The continuous worldwide demand for multi-Gb/s data-rate has driven the rapid development and standardization of 5G New Radio (NR) specifications in the mmwave bands [1]-[3]. As a result, there is a surge of interest in high-performance yet compact mm-wave 5G front-end chipsets to enable large-aperture phased arrays. In User Equipment (UE) devices, the limited form factor restricts the number of antenna array elements, e.g., 2×2, which dramatically increases the output power (Pout) requirement per element [1], [4]. For base stations, although some applications require only moderate element Pout and high antenna gain, high Pout capabilities allow array-divisions/sub-arrays for concurrent multi-stream mmwave links.

NASA/DoD Workshop on Evolvable Hardware

作者： J. Plante H. Shaw L. Mickens C. Johnson-Bey Dynamic Range Corporation Office of Parts Packaging and Assembly Technologies NASA Goddard Space Flight Center USA ARCADE Laboratory Morgan State University USA

The recent commercial availability of field programmable analog arrays (FPAAs) is leading designers of high reliability space and ground support systems to consider how these devices can lead to new applications. They hold promises for analog systems that require reactive evolvability such as those that correct defective mechanical deployments. They are also suited to evolving circuits, which change with temporary or degenerative electrical conditions such as those associated with power systems during specific periods of orbit in space flight and with the effects of aging on electronic components. FPAAs are seen as a key enabler to a system in development that will enable circuit development in a hardware environment that can be programmed and tailored for a given system's electrical input/output/load environment.

International conference on ASIC

作者： Yanyan Qiu Center for Microsystem Instituto Superior Técnico Lisboa Portugal

solid state sensors provide an indispensable link for gathering, processing, and communicating information between microsystems, users and the nonelectronic world. As the microsystem technology rapidly gains importance in the market, solid-state sensors have become an important key factor on determining the performance of the microsystem and opening new market area for future VLSI (very-large-scale-integrated) systems. Significant advances have been made in developing new integrated sensors and microsystems, for example, sensors for measuring pressure, acceleration, flow, image, vibration, strain, sound, and many others have been developed. This paper will briefly review the state-of-the-art in integrated sensors and microsystems. The application of integrated circuit (IC) technology to microsensors is also addressed. In addition, as an example, this paper will give a short description on the basic principles and applications of humidity sensors. Moreover, sensors market development are presented in the end.

The world is simply less colorful, without the sense of colour. In ordinary life, a difference in colour perception is mostly inconsequential. However, in many industries, the ability to sense colour precisely can be crucial. In this paper, a novel reflective colour sensing system is presented for process monitoring and control applications in paper and textile industries. The system is developed using a solid state RGB sensor and a smart signal processing algorithm implemented on micro-controller architecture. A hybrid neural network comprising Self organizing mapping and Back propagation architecture is used for colour zone classification and exact colour identification of papers. Demonstrator applications and simulation results are discussed to highlight the importance of sensor and accuracy in measurement.

The open array chip is an incredibly valuable tool for analyzing single molecule levels. Its efficiency, speed, compatibility, and precision make it an essential part of this process. However, efficient sample addition has become a significant challenge in the development of open array chips due to the coupling of the solid-liquid interface and the need for high-precision control. To address this challenge, we have developed an integrated adding sample device using technology of generates and detects controllable droplets array based on an open array chip with a biomimetic structure. This device combines a microfluidic chip, image detection, and smear speed regulation. We have studied the factors that affect the efficiency of sample loading, such as the number, speed and fluctuation of smears, and microwell size. The experiments have shown that the open array chip with the microwell’s diameter of 350 µm can generate arrays of ~470/cm2 ~8 nL droplets, significantly reducing controlled speed fluctuation errors by7.24% and volume fluctuation errors by 24% compared to traditional manual ways. The device has also displayed excellent performance on chips with microwell diameters of 120, 350, 700, and 1300 µm, respectively, with a notable first-time success rate of up to 91% on chips with microwell diameters of 120 µm. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2023.

A hybrid microelectronics solid state relay was developed in a TO-116 package for the MINX project. The relay provides 2500 V dc input to output isolation and operated from a MHTL logic signal to switch a load of 400 V dc at 2 mA. The relay is designed to operate in space and survive 1000 thermal cycles of -120° C to 80° C. The use of X-rays for failure analysis in small hybrid circuits proved valuable and the applications of vacuum deposited Parylene 1 as a dielectric coating proved extremely valuable.

development of Amperometric Glucose Biosensor Based on Prussian Blue Functionlized TiO₂ Nanotube arrays

Amperometric biosensors consisting of oxidase and peroxidase have attracted great attention because of their wide application. The current work demonstrates a novel approach to construct an enzymatic biosensor based on TiO2 nanotube arrays (TiNTs) as a supporting electrode on which Prussian Blue (PB)-an "artificial enzyme peroxidase" and enzyme glucose oxidase (GOx) have been immobilized. For this, PB nanocrystals are deposited onto the nanotube wall photocatalytically using the intrinsic photocatalytical property of TiO2, and the GOx/AuNPs nanobiocomposites are subsequently immobilized into the nanotubes via the electrodeposition of polymer. The resulting electrode exhibits a fast response, wide linear range, and good stability for glucose sensing. The sensitivity of the sensor is as high as 248 mA M-1 cm(-2), and the detection limit is about 3.2 mu M. These findings demonstrate a promising strategy to integrate enzymes and TiNTs, which could provide an analytical access to a large group of enzymes for bioelectrochemical applications including biosensors and biofuel cells.

With the increasing demand of the accuracy of direction of arrival (DOA) estimation, the spare array configurations have attracted considerable interest because of their ability of possessing increased array aperture and enhanced degrees of freedom (DOF). In this paper, we propose an augmented extended nested array (AENA) strategy based on the different co-array (DCA) theory. The AENA configuration consists of a sparse uniform linear array (ULA) and two sparse nonuniform linear arrays (NLAs) with sensor locations being determined by relative position. Compared with other existing sparse arrays, the significant advantage of AENA configuration is its ability of processing a higher number of consecutive DOF. And simulation results have confirmed the superiority that our proposed AENA configuration can furtherly reduce the root mean square error (RMSE) in DOA estimation, compared with the other nested-like array configurations.
