Analysis and design of transformer-based CMOS ultra-wideband millimeter-wave circuits for wireless applications: a review Review Articles

Yi-ming YU, Kai KANG

Frontiers of Information Technology & Electronic Engineering 2020, Volume 21, Issue 1, Pages 97-115 doi: 10.1631/FITEE.1900491

Abstract: With a lot of millimeter-wave (mm-Wave) applications being issued, wideband circuits and systems have attracted much attention because of their strong applicability and versatility. In this paper, four transformer-based ultra-wideband mm-Wave circuits demonstrated in CMOS technologies are reviewed from theoretical analysis, implementation, to performance. First, we introduce a mm-Wave low-noise amplifier with transformer-based Gm-boosting and pole-tuning techniques. It achieves wide operating bandwidth, low noise figure, and good gain performance. Second, we review an injection-current-boosting tech-nique which can significantly increase the locking range of mm-Wave injection-locked frequency triplers. Based on the injection- locked principle, we also discuss an ultra-wideband mm-Wave divider with the transformer-based high-order resonator. Finally, an E-band up-conversion mixer is presented; using the two-path transconductance stage and transformer-based load, it obtains good linearity and a large operating band.

A 9.8–30.1 GHz CMOS low-noise amplifier with a 3.2-dB noise figure using inductor- and transformer-based

Hongchen Chen, Haoshen Zhu, Liang Wu, Wenquan Che, Quan Xue,hongdoublechen@gmail.com,zhuhs@scut.edu.cn,wuliang@cuhk.edu.cn,eewqche@scut.edu.cn,eeqxue@scut.edu.cn

Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 4, Pages 586-598 doi: 10.1631/FITEE.2000510

Abstract: A 9.8–30.1 GHz (LNA) with a 3.2-dB minimum noise figure (NF) is presented. At the architecture level, a topology based on (CG) cascading with a common-source (CS) amplifier is proposed for simultaneous wideband input matching and relatively high gain. At the circuit level, multiple techniques are proposed to improve LNA performance. First, in the CG stage, loading effect is properly used instead of the conventional feedback technique, to enable simultaneous impedance and noise matching. Second, based on in-depth theoretical analysis, the inductor- and -based techniques are employed for the CG and CS stages, respectively, to enhance the gain and reduce power consumption. Third, the floating-body method, which was originally proposed to lower NF in CS amplifiers, is adopted in the CG stage to further reduce NF. Fabricated in a 65-nm technology, the LNA chip occupies an area of only 0.2 mm and measures a maximum power gain of 10.9 dB with −3 dB bandwidth from 9.8 to 30.1 GHz. The NF exhibits a minimum value of 3.2 dB at 15 GHz and is below 5.7 dB across the entire bandwidth. The LNA consumes 15.6 mW from a 1.2-V supply.

Bisimulation-based stabilization of probabilisticBoolean control networkswith state feedback control Research Articles

Nan JIANG, Chi HUANG, Yao CHEN, Jürgen KURTHS

Frontiers of Information Technology & Electronic Engineering 2020, Volume 21, Issue 2, Pages 268-290 doi: 10.1631/FITEE.1900447

Abstract: This study is concerned with probabilistic Boolean control networks (PBCNs) with state feedback control. A novel definition of bisimilar PBCNs is proposed to lower computational complexity. To understand more on bisimulation relations between PBCNs, we resort to a powerful matrix manipulation called semi-tensor product (STP). Because stabilization of networks is of critical importance, the propagation of stabilization with probability one between bisimilar PBCNs is then considered and proved to be attainable. Additionally, the transient periods (the maximum number of steps to implement stabilization) of two PBCNs are certified to be identical if these two networks are paired with a bisimulation relation. The results are then extended to the probabilistic Boolean networks.

Li Hongbin,Zhang Chenghui,Song Jun

Strategic Study of CAE 2001, Volume 3, Issue 9, Pages 52-57

Abstract:

The paper analyzes common methods for the optimal scheduling modeling problem of variable-pressure variable-flow operation of inverter-drive pumps connected in parallel and compares the merits and defects of them. In the common method, the objective function is the shaft horsepower of the pumps and the constrained conditions are water supply target and high-efficiency area of pumps. In another method, the objective function is the square of the difference between the actual and needed flow when satisfying the lift target and the constrained conditions are high-efficiency areas of pumps. The paper proposes a new modeling method, which is compatible with the actual operation and has higher precision and satisfies the engineering requirement on lower switching frequency. Simulation results have proved its validity.

Wei Xin, Li Ming, Li Jian, Wang Chao, Li Chuanchuan

Strategic Study of CAE 2020, Volume 22, Issue 3, Pages 21-28 doi: 10.15302/J-SSCAE-2020.03.004

Abstract:

As the basis of the whole laser industry, the semiconductor laser industry is not only large-scaled but also has strong radiation and driving capacities. The semiconductor lasers are widely used in industrial, military, and living consumption fields such as optical communication, optical information processing, novel manufacturing, laser display, and biological and medical sensing. To adapt to the gradually expanding application range and satisfy the new requirements of different application scenarios, various new mechanisms, concepts, and structures have been introduced into the semiconductor laser industry through interdisciplinary penetration, greatly optimizing the wavelength coverage, beam quality, device volume, power consumption, modulation speed, and output power of the semiconductor lasers. This paper introduces several rapidly developed new semiconductor lasers by comparing their physical connotation, structural design, and preparation methods. Considering the current development status of related industries in China, we suggest that the development of the semiconductor laser industry should be closely combined with industrial application. The performance of the semiconductor lasers should be optimized in a closed-loop manner relying on the market capacity and the strong systematic development ability in China to promote the key technologies. New principles, structures, and processes should be continually introduced into this industry through interdisciplinary integration. Meanwhile, using the policy-oriented advantages in China, we suggest to increase investment in vertical external cavity surface emitting lasers, micro-nano lasers, and topological insulator lasers and conduct mass production and controllable production, thus to seize the leading position in international competition in the related fields.

Analysis and Study of New Type Hydrostatic Bearing Restrictor With Very Good Restrictive Performance

Meng Xinzhai,Meng Zhaoyan

Strategic Study of CAE 2005, Volume 7, Issue 3, Pages 49-52

Abstract:

The new type restrictor of hydrostatic bearing has many good and useful restrictive performances： ①According to the analysis in this paper, the restrictive parameter index must be preserved b≥3.② When extra load forced on the bearing fluid pocket, the pocket pressure is increased by the additional load at once. At this time, the pocket pressure is applied to the end area of valve also. Therefore, the valve will be changed along axis by the increased fluid pressure. The incremental value of restrictive parameter will be increased at the same time. As a result, the new type restrictor will be supplied with more fluid flow. The bearing clearance may maintain nearly constant. ③There are three new types of restrictors： new type variable clearance slide valve, new type clearance sheat and new type variable diameter capillary. It has advantages, such as simple construction, low cost and smaller volume.

In addition, for the first time, a reset-based and a with set and reset capabilities are designed. Using the proposed , a new 3-bit is developed which reduces 2.14% cell numbers compared to the best of previous designs. Moreover, based on the 3-bit , a 4-bit is designed, which reduces 0.51% cell numbers and 4.16% cross-section area compared to previous designs. In addition, two selective s are introduced to count from 0 to 5 and from 2 to 5. Simulations were performed using and tools in coherence vector engine mode. The proposed circuits are compared with related designs in terms of delay, cell numbers, area, and leakage power.

Study on Temperature Control of Trace ContaminantControl Subassembly in Manned Spacecraft

Pang Liping,Wang Jun

Strategic Study of CAE 2007, Volume 9, Issue 4, Pages 60-63

Abstract:

The catalytic oxidizer assembly(COA)is an important part of the trace contaminant control subassembly in manned spacecraft. Temperature control in COA via a new self-tuning fuzzy logical controller (FLC)is analyzed in this paper. The new tuning method applies the bang-bang on-line tuned method to the design of the self-tuning FLC for obtaining the system parameters. On the basis of these parameters, the input and output scaling factors are calculated with simple tunable formulas. Then the proposed self-tuning FLC is realized by combining the scaling factors and the normal look-up table. It can realize self-tuning parameters, and simplify the design. Simulation results show that the proposed self-tuning FLC is fit for controlling the temperature of COA and isn't sensitive to parameter changes.

Controller area network node reliability assessment based on observable node information Article

Lei-ming ZHANG, Long-hao TANG, Yong LEI

Frontiers of Information Technology & Electronic Engineering 2017, Volume 18, Issue 5, Pages 615-626 doi: 10.1631/FITEE.1601029

Abstract: Controller area network (CAN) based fieldbus technologies have been widely used in networked manufacturing systems. As the information channel of the system, the reliability of the network is crucial to the system throughput, product quality, and work crew safety. However, due to the inaccessibility of the nodes’ internal states, direct assessment of the reliability of CAN nodes using the nodes’ internal error counters is infeasible. In this paper, a novel CAN node reliability assessment method, which uses node’s time to bus-off as the reliability measure, is proposed. The method estimates the transmit error counter (TEC) of any node in the network based on the network error log and the information provided by the observable nodes whose error counters are accessible. First, a node TEC estimation model is established based on segmented Markov chains. It considers the sparseness of the distribution of the CAN network errors. Second, by learning the differences between the model estimates and the actual values from the observable node, a Bayesian network is developed for the estimation updating mechanism of the observable nodes. Then, this estimation updating mechanism is transferred to general CAN nodes with no TEC value accessibility to update the TEC estimation. Finally, a node reliability assessment method is developed to predict the time to reach bus-off state of the nodes. Case studies are carried out to demonstrate the effectiveness of the proposed methodology. Experimental results show that the estimates using the proposed model agree well with actual observations.

Fuzzy impedance control of an electro-hydraulic actuator with an extended disturbance observer Regular Papers-Research Articles

Ming-jie LI, Jian-hua WEI, Jin-hui FANG, Wen-zhuo SHI, Kai GUO

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 9, Pages 1221-1233 doi: 10.1631/FITEE.1800155

Abstract: In this paper, we deal with both velocity control and force control of a single-rod electro-hydraulic actuator subject to external disturbances and parameter uncertainties. In some implementations, both velocity control and force control are required. Impedance control and an extended disturbance observer are combined to solve this issue. Impedance control is applied to regulate the dynamic relationship between the velocity and output force of the actuator, which can help avoid impact and keep a proper contact force on the environment or workpieces. Parameters of impedance rules are regulated by a fuzzy algorithm. An extended disturbance observer is employed to account for external disturbances and parameter uncertainties to achieve an accurate velocity tracking. A detailed model of load force dynamics is presented for the development of the extended disturbance observer. The stability of the whole system is analyzed. Experimental results demonstrate that the proposed control strategy has not only a high velocity tracking performance, but also a good force adjustment performance, and that it should be widely applied in construction and assembly.

Process Intensification in Pneumatically Agitated Slurry Reactors Review

Shujun Geng, Zai-Sha Mao, Qingshan Huang, Chao Yang

Engineering 2021, Volume 7, Issue 3, Pages 304-325 doi: 10.1016/j.eng.2021.03.002

Abstract:

Pneumatically agitated slurry reactors, including bubble column reactors and airlift loop reactors (ALRs), are important gas–liquid–solid multiphase reactors. These reactors have been widely applied in many processes, especially in the biological fermentation and energy chemical industry, due to their low shear stress, good mixing, perfect mass-/heat-transfer properties, and relatively low costs. To further improve the performance of slurry reactors (i.e., mixing and mass/heat transfer) and to satisfy industrial requirements (e.g., temperature control, reduction of back-mixing, and product separation), the process intensification of slurry reactors is essential. This article starts by reviewing the latest advancements in the intensification of mixing and mass/heat transfer in these two types of reactors. It then summarizes process-intensification methods for mixing and separation that allow continuous production in these slurry reactors. Process-intensification technology that integrates directional flow in an ALR with simple solid–liquid separation in a hydrocyclone is recommended for its high efficiency and low costs. This article also systematically addresses vital considerations and challenges, including flow regime discrimination, gas spargers, solid particle effects, and other concerns in slurry reactors. It introduces the progress of numerical simulation using computational fluid dynamics (CFD) for the rational design of slurry reactors and discusses difficulties in modeling. Finally, it presents conclusions and perspectives on the design of industrial slurry reactors.
