Research on Heat Dissipation Performance of Battery Modules Incorporating PCM and Fin Structures
Mingxi Chen;Biao Jin;Jiaji Chen;Kairui Li;Chenxi Yuan;Tong Zhang;Qiang Fei
2024 8th International Conference on Electrical, Mechanical and Computer Engineering (ICEMCE)
Year: 2024 | Conference Paper |
To address the issues of excessive and non-uniform temperature distributions in lithium-ion battery modules under extreme operating conditions, a novel thermal management strategy integrating phase change material (PCM) with an optimized finned aluminum plate has been proposed. A comprehensive two-dimensional thermal model, incorporating detailed heat generation dynamics of individual cells, heat ...Show More
A Compact Low-power 16b SAR ADC using Reservoir-Charge-Redistributed DAC and Configurable Floating-Inverter-Based Comparator
Chenxi Yuan;Xianghui Pan;Zihao Zheng;Yan Song;R. P. Martins;Yan Zhu;Chi-Hang Chan
2024 IEEE Asian Solid-State Circuits Conference (A-SSCC)
Year: 2024 | Conference Paper |
Systems-on-chip applications have become imperative for high-precision ADCs with low power consumption and compact silicon area. SAR ADCs exhibit outstanding energy efficiency but necessitate high fidelity and fast settling reference voltages, often consuming considerable power and/or area. To alleviate such overheads, the passive-charge-sharing SAR ADCs have been reported [1] [2] [3], as shown in...Show More
Self-Terminating Write of Multi-Level Cell ReRAM for Efficient Neuromorphic Computing
Zongwu Wang;Zhezhi He;Rui Yang;Shiquan Fan;Jie Lin;Fangxin Liu;Yueyang Jia;Chenxi Yuan;Qidong Tang;Li Jiang
2022 Design, Automation & Test in Europe Conference & Exhibition (DATE)
Year: 2022 | Conference Paper |
The Resistive Random-Access-Memory (ReRAM) in crossbar structure has shown great potential in accelerating the vector-matrix multiplication, owing to the fascinating computing complexity reduction (from O(n2) to O(1)). Nevertheless, the ReRAM cells still encounter device programming variation and resistance drifting during computation (known as read disturbance), which significantly hamper its ana...Show More
A Cross-Coupled Active Rectifier-Booster Regulator Integrated Circuit for Broadband Wireless Energy Harvesting System
Shiquan Fan;Chenxi Yuan;Wu Miao;Raja Usman Tariq;Ming Ye;Zheyi Yuan;Li Geng
2020 IEEE MTT-S International Wireless Symposium (IWS)
Year: 2020 | Conference Paper |
Cited by: Papers (2)
In this paper, a fully integrated 3-stage active recti-fier-booster regulator (RBR) is proposed. The discrete diodes which used in conventional RBR structure are completely replaced by standard power PMOS and NMOS in the new topology to realize fully integration. Cross-coupled driving technique is adopted to achieve self-driving of the power MOS switches without any additional functional circuit. ...Show More
Design of Improved KY Converter with Low Power ZCD Circuit for Wide Load Current Application
2020 IEEE International Conference on Integrated Circuits, Technologies and Applications (ICTA)
Year: 2020 | Conference Paper |
Cited by: Papers (1)
In this paper, an improved KY converter with pulse width modulation (PWM) is proposed. The reverse current paths under discontinuous-conduction mode (DCM) are analyzed. To eliminate the reverse current exactly, a noval zero current detection (ZCD) method is proposed and demonstrated. The KY converter is fabricated by using 0.18 μm BCD process with active area of 3.4 mm2. The off-chip components of...Show More
A 100mV Input Voltage, Multi-step Self-Startup Boost Converter Achieving 50X Voltage Step-up with Standard 0.18 μm CMOS Process for Energy Harvesting application
2020 IEEE International Conference on Integrated Circuits, Technologies and Applications (ICTA)
Year: 2020 | Conference Paper |
In this paper, a multi-step self-startup boost converter is proposed for energy harvesting application. To decrease the minimum startup voltage, novel body-effect control method of MOSFETs is applied to self-startup circuit. Besides, dual-phase charge pump is adopted to reduce the output ripple. In addition, multi-step startup strategy is proposed to realize self-startup process of the boost conve...Show More
A 100 MHz, 0.8-to-1.1 V, 170 mA Digital LDO With 8-Cycles Mean Settling Time and 9-Bit Regulating Resolution in 180-nm CMOS
This brief presents an all-digital low dropout regulator (DLDO) with high regulating resolution and fast transient tracking by combining novel interval-searching algorithm and recover acceleration techniques. By bringing forth an enhanced interval-searching algorithm (ISA) with 9-bit register regulating precision, the output can be stabilized within 8 cycles when the load changes. A recover accele...Show More
