A High Performance Silicon-on-Insulator LDMOSTT Using Linearly Increasing Thickness Techniques

Chinese Physics Letters 2010年第6期27卷 179-182页

We present a new technique to achieve uniform lateral electric field and maximum breakdown voltage in lateral double-diffused metal-oxide-semiconductor transistors fabricated on silicon-on-insulator substrates. A linearly increasing drift-region thickness from the source to the drain is employed to improve the electric field distribution in the devices. Compared to the lateral linear doping technique and the reduced surface field technique, twodimensional numerical simulations show that the new device exhibits reduced specific on-resistance, maximum off- and on-state breakdown voltages, superior quasi-saturation characteristics and improved safe operating area.

Analytical models of lateral power devices with arbitrary vertical doping profiles in the drift region

引用

Chinese Physics B 2013年第5期22卷 595-603页

作者：花婷婷郭宇锋于映 Gene sheu 蹇彤姚佳飞 College of Electronic Science and Engineering Nanjing University of Posts and Telecommunications Department of Computer Science & Information Engineering Asia University

By solving the 2D Poisson＇s equation, analytical models are proposed to calculate the surface potential and electric field distributions of lateral power devices with arbitrary vertical doping profiles. The vertical and the lateral breakdown voltages are formulized to quantify the breakdown characteristic in completely-depleted and partially-depleted cases. A new reduced surface field （RESURF） criterion which can be used in various drift doping profiles is further derived for obtaining the optimal trade-off between the breakdown voltage and the on-resistance. Based on these models and the numerical simulation, the electric field modulation mechanism and the breakdown characteristics of lateral power devices are investigated in detail for the uniform, linear, Gaussian, and some discrete doping profiles along the vertical direction in the drift region. Then, the mentioned vertical doping profiles of these devices with the same geometric parameters are optimized, and the results show that the optimal breakdown voltages and the effective drift doping concentrations of these devices are identical, which are equal to those of the uniform-doped device, respectively. The analytical results of these proposed models are in good agreement with the numerical results and the previous experimental results, confirming the validity of the models presented here.

An efficient semi-blind source extraction algorithm and its applications to biomedical signal extraction

引用

Science in China(Series F) 2009年第10期52卷 1863-1874页

作者： YE YaLan sheu Phillip C-Y ZENG JiaZhi WANG Gang LUKe School of Computer Science and Engineering University of Electronic Science and Technology of China Chengdu 610054 China Department of Electrical Engineering and Computer Science University of California Irvine CA 92697-2625 USA School of Life Science and Technology University of Electronic Science and Technology of China Chengdu 610054 China

In many applications, such as biomedical engineering, it is often required to extract a desired signal instead of all source signals. This can be achieved by blind source extraction （BSE） or semi-blind source extraction, which is a powerful technique emerging from the neural network field. In this paper, we propose an efficient semi-blind source extraction algorithm to extract a desired source signal as its first output signal by using a priori information about its kurtosis range. The algorithm is robust to outliers and spiky noise because of adopting a classical robust contrast function. And it is also robust to the estimation errors of the kurtosis range of the desired signal providing the estimation errors are not large. The algorithm has good extraction performance, even in some poor situations when the kurtosis values of some source signals are very close to each other. Its convergence stability and robustness are theoretically analyzed. Simulations and experiments on artificial generated data and real-world data have confirmed these results.
