Spectral radiation imaging diagnostic systems utilizing PDA (avalanche PhotoDiode Array) have been developed and deployed on the HFRC device (HUST Field Reversed Configuration Device). These systems are designed to measure Hα radiation imaging, plasma velocity, orientation, and shape. Their innovative features include higher spatial resolution, integrated system design, flexible measurement, and superior electronic performance. This paper discusses the selection of basic electronic circuits, circuit analysis, parameter design, and noise analysis in detail. The accuracy of the design is validated through simulation and practical testing. The final system parameters achieved a bandwidth of 610 kHz, low noise of 2.5 mV, approximately 3% system overshoot, and a rising time of 468.5 ns. Additionally, preliminary measurement results are provided. © Published under licence by IOP Publishing Ltd.

A combined multi-pulse transmitting circuit for time domain electromagnetic detection is proposed in this paper. The dual-pulse energy boosting and high-voltage clamping technology are employed in transmitting system to meet the requirements of large detection depth and high resolution in shallow strata simultaneously. The operation principles of the proposed topology are explained and the simplified control method is provided. simulation results demonstrate that the circuit can generate high-quality combined current pulses for the highly inductive load. Extensive experiments verify that the proposed circuit and control method can improve the reliability and efficiency of the transmitting system and it is suitable for TEM application. © 2023 IEEE.

The demand for computation driven by machine learning and deep learning applications has experienced exponential growth over the past five years (Sevilla et al 2022 2022 international Joint conference on Neural Networks (IJCNN) (IEEE) pp 1-8), leading to a significant surge in computing hardware products. Meanwhile, this rapid increase has exacerbated the memory wall bottleneck within mainstream Von Neumann architectures (Hennessy and Patterson et al 2011 Computer architecture: a quantitative approach (Elsevier)). For instance, NVIDIA graphical processing units (GPUs) have gained nearly a 200x increase in fp32 computing power, transitioning from P100 to H100 in the last five years (NVIDIA Tesla P100 2023 (***/en-us/data-center/tesla-p100/);NVIDIA H100 Tensor Core GPU 2023 (***/en-us/data-center/h100/)), accompanied by a mere 8x scaling in memory bandwidth. Addressing the need to mitigate data movement challenges, process-in-memory designs, especially resistive random-access memory (ReRAM)-based solutions, have emerged as compelling candidates (Verma et al 2019 IEEE Solid-State circuits Mag. 11 43-55;Sze et al 2017 Proc. IEEE 105 2295-329). However, this shift in hardware design poses distinct challenges at the design phase, given the limitations of existing hardware design tools. Popular design tools today can be used to characterize analog behavior via SPICE tools (PrimeSim HSPICE 2023 (***/implementation-and-signoff/ams-simulation/***)), system and logical behavior using Verilog tools (VCS 2023 (***/verification/simulation/***)), and mixed signal behavior through toolbox like CPPSIM (Meninger 2023 (***/Tutorials/wideband_fracn_***)). Nonetheless, the design of in-memory computing systems, especially those involving non-CMOS devices, presents a unique need for characterizing mixed-signal computing behavior across a large number of cells within a memory bank. This requirement f

28th international conference on Mixed Design of Integrated circuits and system (MIXDES)

作者： Kielbik, Rafal Halagan, Krzysztof Rudnicki, Kamil Polanowski, Piotr Jablonski, Grzegorz Jung, Jaroslaw Lodz Univ Technol Dept Microelect & Comp Sci Lodz Poland Lodz Univ Technol Dept Mol Phys Lodz Poland Brightelligence Sp Zoo Lodz Poland

ISBN: (纸本)9788363578190

In this paper, the implementation of a molecular diffusion model named Dynamic Lattice Liquid (DLL) is discussed. Two algorithms, sequential and parallel, implementing this model are examined. The presented theoretical considerations indicate sonic limitations of the sequential approach. The proposed parallel algorithm overcomes these limitations, hut it requires dedicated hardware to function. An example of such hardware, the FPGA-based HPC system named ARUZ, is presented.

Using CST simulation software, a sheet beam electron gun with U=33kV and I=0.68A was designed to meet the high-power requirements of the W-band sheet beam traveling-wave tube. The waist size of the elliptical sheet beam is 1.2mm*0.18 mm. The PCM structure with offset pole is used in the matching focusing magnetic system. The results show that in a 1.75mm*0.4mm rectangular channel, the elliptical sheet electron beam can be transmitted 100mm without interception. To shorten the design cycle of PCM, the rectangular current coil equivalent circuit was adopted to calculate the axial magnetic field Bz. The theoretical calculation results are consistent with the CST simulation. © 2022 IEEE.

ARUZ (Analizator Rzeczywistych Ukladow Zlozonych, Analyser of Real Complex systems) is a massively parallel FPGA-based simulator located at BioNanoPark Lodz. This machine has been designed to reflect the Dynamic Lattice Liquid (DLL) algorithm in hardware. In this paper, FPGA implementation details are presented for DLL functionality extension. This extension allows taking into account potential energy barriers in molecular simulations performed on ARUZ and thus modeling thermally-activated diffusion processes in liquids.

A design scheme of Duffing Chaotic circuit module is proposed based on Multisimin study. The operational amplifier is used to construct integrating circuit. The Duffing chaotic circuit is also designed based on the integrating circuit. The results can be shown in a virtual oscilloscope by phase trajectory. The bifurcation results of Duffing oscillator solved by the circuit module are consistent with that obtained by Matlab. The Duffing equation in critical state is selected as Chaos Inspection system (CIS), which is used to identify weak signal with strong noise. simulation examples show that the chaotic circuit designed in this study can successfully identify many kinds of weak signals, such as sine wave, triangle wave, and square wave etc. This work provides a theoretical basis for the hardware of CIS of weak signal with strong noise.
