This paper presents a high-performance self-starting reference current source capable of operating in high-voltage scenarios. By employing loop control and segmented current control, it addresses the issues of poor performance in conventional high-voltage references and the need for external startup signals. In terms of voltage endurance, the reference source utilizes high-voltage transistor isolation to maintain high-voltage tolerance, while the core reference operates using low-voltage devices, thus avoiding the performance drawbacks associated with high-voltage components. Moreover, the startup sequence involves constant current charging followed by constant voltage charging, facilitating smooth and controllable self-starting. The design is implemented using a 0.18 μ m process. The circuit's maximum input voltage is 26V, with a power supply rejection ratio (PSRR) of 78.8dB, a line regulation of 0.22%/V, a temperature coefficient (TC) of 8.96 ppm/°C for the -40 °C to 125°C temperature range and a power consumption of 7.5μ A. © 2024 IEEE.

At present, the trusted platform module (TPM) has been widely used in electricity, finance, transportation, and other industries, and its security has attracted much attention. The research on the side-channel attack (SCA) can be conducive to improving the security design technology of trusted platform modules. The side channel attack on the trusted platform module is studied from the initial differential power analysis (DPA) to the machine learning method. This paper introduces the deep learning techniques in SCA and proposes a new SCA technique based on deep learning. Firstly, on basis of the characteristics of SCA on TPM, we improve the convolutional neural network (CNN) models, including ResNet, VGG, and Google Net. Then, for the SM4 cipher implemented with and without countermeasures, we implement some attack experiments by exploiting the SCA based on various deep learning models and compare the experimental results with the DPA attack. The experiment results show that under the same circumstance, the SCA based on the deep learning method is more effective. We compare the effects of different CNN models and hyper-parameters to provide the basis and data for further research. © 2022 Institute of Physics Publishing. All rights reserved.

The high-frequency transformer (HFT) plays a crucial role in DC/DC converters, necessitating an appropriate design to achieve optimal efficiency and power density. This study presents a novel design technique that combines scanning and multi-objective optimization. To convert the multiple objectives into a single objective optimization problem, we employ a weighting method while considering the interplay between leakage inductance and DC/DC converter parameters. The effectiveness of our proposed design methodology is validated through the development of a 10kHz/200kVA HFT prototype. The design method proposed in this paper was validated through prototype testing, demonstrating its effectiveness and accuracy, thereby holding significant engineering implications for the development of HFT. © 2024 IEEE.

eDRX has been introduced in 3GPP Release 17 for RedCap device as a key feature for optimizing UE power saving. This paper investigate the energy consumption factor and wake up delay of eDRX mechanism under different configuration parameters of RedCap device, a new type of low-cost device, which are applied in IOT, especially those scenarios with high energy efficiency. We study the theoretical calculation method of energy consumption saving factor and wake up delay when RedCap device is in RRC idle state, the traffic dada arrival rate follows the exponential distribution. We also verify the theoretical model by system simulation. Considering the tradeoff between energy consumption and wake up delay under actual traffic arrival rate, we give the recommended value of eDRX configuration parameters. © 2023 SPIE.

The reliability design and analysis methods, which are pertinent to the traction power supply systems in weak grid, are far from perfect. The current results fail to offer a comprehensive assessment of the system's reliability. In this paper, by optimizing node number and parent node search method, a fault impact assessment method is proposed to classify each node according to the influence range and isolation range of shutdown components, which can achieve the accumulation of system reliability indicators and achieve the goal of evaluating the reliability of the whole system. In addition, this paper presents a method to quickly calculate the reliability of the system and the fault importance of each component by using Goal-Oriented (GO) method, and verifies the effectiveness of the proposed method with an example. The results show that the average error of the average downtime rate and the average downtime time is 4.09% and 5.33% respectively, which is within the error range. © 2024 IEEE.
