Abstract:With the development of chip manufacturing technology and packaging technology, the device integration and signal speed inside electronic products continue to increase, and microsystems become an emerging form, which leads to increasing requirements for power integrity. Unreasonable power supply integrity design will bring great interference to power quality and signal quality, and even make the system collapse. In this paper, the power supply integrity of the designed multi-chip microsystem was simulated, and the PDN impedance was optimized by the collaborative decoupling of substrate and PCB decoupling capacitor network, which solved the contradiction between the limited space inside the microsystem and the large demand for decoupling capacitor, and ensured the power supply integrity of the microsystem.

Abstract:In order to improve the calibration efficiency of inter-channel error of multi-channel receiver,a digital comb spectrum calibration source module with low peak to average power ratio(PAPR) is designed and implemented. This module is based on the hardware structure of FPGA+DAC and uses the DDS principle to generate comb spectrum signal. In order to reduce the PAPR of the comb spectrum signal, the genetic algorithm is used to optimize the initial phase of each subcarrier of the signal, and a group of initial phase combination which is better than the algebraic suboptimal solution is calculated. The PAPR is reduced from 4.98 dB of the suboptimal solution to 3.98 dB, and the subcarrier power and outside pass-band spur suppression of the comb spectrum signal are improved, optimizing the signal quality of the comb spectrum module. When the output range of the comb spectrum signal is170 MHz ~230 MHz with the spectrum interval of 1 MHz, the subcarrier power is -35.5 dBm and the outside pass-band spur suppression is 64 dBc, which fully meets the requirements of the calibration source.

Abstract:When integrating multi-channel high-speed ADC (Analog-to-Digital Converter) with LVDS (Low Voltage Differential Signal) interface in SIP (System In a Package) system, it is faced with the problem of clock-to-data skew, data-to-data skew, accumulated clock jitter and so on caused by different LVDS channel with different delays. Therefore, a multi-channel LVDS receiver was designed in this paper which can adaptively adjust the skew of each LVDS channel. The receiver uses data clock recovery technology to generate eight multi-phase sampling clocks, combining with ADC test mode to confirm the sampling phase of each channel, the delay of each channel can be automatically adjusted, aiming to align the sampling phase of channels and ensure the data correct. Finally, the receiver was designed, simulated, and realized based on advanced CMOS technology. The results of simulation and chip test show that the receiver can automatically adjust the delay of each channel to align the sampling phase, the maximum range of sampling phase adjustment is ± 3 bit, and the signal-to-noise ratio is greater than 65 dB, which meets the design requirements and application requirements.

Abstract:The traditional methods for testing the frequency of quartz crystal resonators include indirect calculation method, signal source oscillation method, and network analyzer method, each of which has significant shortcomings. This article proposes three new testing methods based on the frequency characteristics of quartz crystal resonators: oscilloscope testing method, frequency meter testing method, and spectrograph testing method. These three methods differ in basic testing principles, equipment configuration requirements, testing accuracy, and applicable environments. This article provides a detailed comparison of the advantages and disadvantages of these three methods, and proposes selection suggestions for different application conditions. If only the frequency of quartz crystal resonators needs to be measured, the spectrograph testing method can be used. If it is necessary to measure the frequency and know the characteristics of the frequency, it is advisable to use the frequency meter testing method. The testing rules of oscilloscopes can be used for rough measurement of the qualitative frequency of quartz crystal resonators. In addition, the possibility of instrument collaboration testing has been explored based on their respective advantages.

Abstract:The design of new malicious code is becoming increasingly complex, and traditional recognition and detection methods can no longer meet current requirements. Therefore, based on the analysis of the BODMAS dataset, this paper performs visualization processing and classification. At the same time, considering that the existing malware visualization classification models mainly rely on global features, this paper designs a CA (Channel-level local feature Attention) module and a MA (Multi-scale local feature Attention) module based on the convolutional neural network, and constructs two new models that cleverly combine global and local features. On the BODMAS dataset, the new models have achieved an increase in the average accuracy of recognizing and classifying malware types compared to the methods described in the BODMAS dataset paper. This proves the feasibility of dataset visualization and the effectiveness of the new models, providing important data and experimental basis for future research.

Abstract:The classification research of visual charts holds significant implications for chart comprehension and document parsing. This paper has constructed two datasets, each containing 16 common chart types, using web scraping and software generation. These datasets exhibit certain advantages in terms of quantity, type, and stylistic diversity. This paper has also conducted experiments comparing Transformer and Convolutional Neural Network (CNN) architectures on three datasets, and the results indicates that the Transformer architecture has certain advantages in the task of chart classification. Utilizing the Swin Transformer model, this paper designs various data augmentation strategies, not only increasing the generalization of the model, but also introducing the distribution difference. By averaging predictions from models trained with different strategies, there is a significant improvement in classification performance compared to individual models. The ensemble model was tested on 6 test sets, with classification accuracy exceeding 0.9 in all cases. For generated charts with high image quality and simple visual forms, the model's classification accuracy approached 1.

Abstract:With the development of Software Defined Radio(SDR) technology and internet technology, a large number of internet receivers are connected to the internet and can access their spectrum waterfall data at will. Spectral waterfall plot is a way to display the frequency domain and time domain characteristics of signals, visually displaying signals of different frequencies in the form of images. In order to better monitor specific signals in the spectral waterfall plot, it is necessary to intelligently identify specific signals in the spectrogram. This article uses deep learning technology to recognize specific signals in the waterfall spectrum, and the recognition accuracy is more than 90% when the signal-to-noise ratio is more than 5 dB.

Abstract:Maize, a crucial staple crop in China, is frequently beset by production challenges stemming from diseases such as maize Northern Leaf Blight, Southern Corn Leaf Blight, and rust, along with insect pests. These maladies significantly undermine maize yield and quality, presenting a potential menace to agricultural production stability. In recent times, visual disease detection techniques have emerged as pivotal instruments for disease management, offering heightened precision relative to conventional methods. This paper leverages the Mask R-CNN architecture as its foundation, integrating DyHead, Groie, and OHEM modules to augment the model's proficiency in segmenting images containing minute disease manifestations. The enhanced Mask R-CNN model exhibits outstanding performance in disease image segmentation, witnessing a 4% uplift in mean average precision (mAP) and an 8.5% enhancement in accuracy for small object segmentation. Compared to analogous instance segmentation models like YOLOv5 and YOLACT++, this model displays superior prowess. To substantiate the utility of each incorporated module, ablation studies were carried out, revealing their constructive roles. Thus, this methodology furnishes a sturdy theoretical underpinning and technological means for the efficacious and precise detection of maize Northern Leaf Blight.

Abstract:In this paper, a novel optimization design scheme is proposed to solve the cascading mismatch problem of sub-circuits in beamforming chips due to parasitic effects. The optimization design scheme proposed in this paper is a design scheme that realizes impedance “pre-mismatch” by introducing the impedance traction effect of adjacent modules and offsetting it with the cascade impedance mismatch. The theory of the “pre-mismatch” technique is provided in the article and a 4-channel X/Ku-band RF transceiver chip has been fabricated to verify the feasibility and effectiveness of this scheme. Compared to conventional designs, the chip operates within the frequency band of 8 GHz~18 GHz, with the receive and transmit average link gains of 6.5 dB and 14 dB, respectively. Both transceiver link gains are increased by more than 2 dB. The transmit link output power is 21 dBm and power-added efficiency is 15.7%,optimized by 1 dB and 9%. The receive link noise figure of 8.72 dB is reduced by 1.2 dB. The maximum phase-shifted root-means-square errors of the transceiver link are 5.25°and 5.12°, with a decrease of 1.75° and 3.17°.

Design of a chipless RFID sensor for soil moisture monitoring

DOI:10.16157/j.issn.0258-7998.244893

Author:Tai Zhengyi,Ma Runbo

Author Affilications:School of Physics and Electronic Engineering, Shanxi University

Abstract:To improve the flexibility and reliability of soil moisture sensors, a low-cost chipless RFID sensor is designed for wireless monitoring of soil moisture. The sensor consists of three Complementary Split Ring Resonators (CSRR) and two orthogonal broadband circular microstrip patch antennas. Two CSRRs of the same size are closely spaced, which can easily cause coupling between resonators, resulting in more significant changes in resonant frequency in high moisture soil. In addition, the CSRR as a reference resonator is used to eliminate the influence of environmental conditions and improve the reliability of measurement. Two microstrip patch antennas are used for transmitting and receiving signals, achieving wireless sensing function. The Radar Cross Section (RCS) of the sensor with single and double CSRR structures is studied, establishing a linear relationship between soil moisture and the difference in resonance frequency. This relationship has been further confirmed through actual measurements. The experimental results show that the sensor has a sensitivity of 18.2 MHz/%θ at soil moisture ranging from 0% to 12%.

Abstract:Images collected under severe weather conditions have problems such as poor contrast and reduced clarity. The deterioration of image quality limits the accuracy of computer vision and the efficiency of automated tasks. This article proposes an image dehazing algorithm based on contrast limited adaptive histogram equalization (CLHE) and improved multi-scale Retinex (MSR). In this algorithm, the input foggy degraded image is first processed by the CLAHE algorithm and then the MSR algorithm. When processing the image with the MSR algorithm, the Gamma correction factor is introduced to estimate the incident light and the surround function in the algorithm is optimized. The results show that compared with the original image, the image processed by this algorithm has improved the information entropy, average gradient and standard deviation of the image. The hardware circuit was designed and the video real-time dehazing was successfully demonstrated on FPGA, which improved the quality of the video image. A digital analysis of board-level resources and function consumption was conducted, proving that the hardware system in this article belongs to the low-power category.
