Optimization of BSIM3 I-V Model for Double Diffused Drain HV MOSFET

Zheng Ren Shaojian Hu Yanling Shi Zhu Jun Shoumian Chen

This paper presents a technique for modeling double diffused drain high-voltage MOSFET devices (DDD HV MOSFET). I-V measurements have been made by Agilent ICCAP. Based on the difference between DDD HV MOSFET and normal low voltage MOSFET devices (LV MOSFET), the Rd dependency of Vgs is discussed and equations of Rd and delta (the effective V _ds parameter) in the BSIM3v3 model have been optimized. Three parameters are added: Prwg2 which is gate bias quadric coefficient of Rdsw and delta ₁ , delta ₂ which are gate bias coefficients of delta. The optimization has been made on SPICE BSIM3v3 model using SPICE macro model. The contrast between I-V simulated data of optimized HV MOSFET model and the measured data has been made after parameters extraction. They fit very well

An Accurate Arithmetic for On-Chip Spiral Inductors with Gradually Changed Metal Width and Space

Journal of Semiconductors (2006)

Tianxing Luo Yanling Shi Yanfang Ding Shenqun Tang Yun Liu

Compared with conventional passive inductors with fixed metal width and space,an inductor with gradually changed mental width and space is put forward to improve its quality factor.But it is difficult to get accurate inductance with most published formulas such as Jenei formula for such novel structure inductor.An accurate arithmetic is presented,which gets total self-inductance by adding up each turn’s self-inductance and gets mutual-inductance from an average approximate formula.The accuracy and effectiveness are verified by HFSS simulation and experiment measurement.The relative error for this arithmetic compared with HFSS is less than 3%,while compared with experiment measurements less than 4%.These show that it is efficient and valuable for the design of such passive spiral inductor.

A Study on PIN Solar Cell with a-Si:H/mc-Si:H Double-Intrinsic Layer

International Conference of Information Technology, Computer Engineering and Management Sciences (2011)

Zhu Jun Ding Jianning Liqiang Guo

This paper put forward a novel PIN solar cell structure with a-Si: H/uc-Si:H double-intrinsic layer. And by establishing the model of photocurrent density of this structure an optimized thickness and band gap were obtained. The simulating results obtained by inputting the data and parameters into AMPS program indicate that compared to single-junction amorphous silicon solar cells, the microcrystalline silicon layer did not cause changes in cell performance. However, due to the reduction in the amorphous silicon layer' thickness, the light-induced fading effects was well suppressed.

Research on Extracting Directly and Indirectly Copper Mineral Information Using Hyperion Data

Zhang Hankui Dengrong Zhang Zhu Jun Le Yu

This paper aims to extracting the copper mine information using Hyperion data from areas with different land cover condition.The L1 level Hyperion data is first preprocessed including band selection,destriping,atmosphere correction and geometric correction.Then different information extraction methods were adopted according to the different vegetation cover conditions.Spectral angle mapping(SAM) method is applied directly in the open canopy area.In vegetated area,we used a vegetation physiology abnormal indicator,which is calculated by hyperspectral vegetation index,to indicate accumulations of copper ion,then to identify copper mine indirectly.The experimental result shows that using complementary information from these two methods synthetically could benefit to extract the copper mine information in the area even covered by complex vegetation distribution.

Study on 3D bio-stimulating microelectrode array based on flexible substrate

Transducer and Microsystem Technologies (2010)

Zhu Jun

A novel 3D bio-stimulating microelectrode array was designed based on polyimide thin film for implantable artificial retina.Non-silicon MEMS technique was applied o fabricate the flexible microelectrode with the height of 80 μm,which is also bio-compatible and chemical stable.The microelectrode was then released from substrate by PDMS sacrificial layer process and packaged by polyimide and PDMS.Au was eletroplated on the surface of electrodes and pads to obtain bio-compatibility.The electrochemical properties of electrodes was detected by three-electrode method,and the impedance varied at the range of 1.5～0.3 kΩ and at the frequency 10-1～105 Hz.With the advantages of small size,light weight,high reliability and flexibility,the device is suitable for bio-stimulation.

Security analysis of continuous-variable quantum key distribution scheme

Chinese Physics (2007)

Zhu Jun Guangqiang He Guihua Zeng

In this paper security of the quantum key distribution scheme using correlations of continuous variable Einstein–Podolsky–Rosen (EPR) pairs is investigated. A new approach for calculating the secret information rate ΔI is proposed by using the Shannon information theory. Employing an available parameter F which is associated with the entanglement of the EPR pairs, one can detect easily the eavesdropping. Results show that the proposed scheme is secure against individual beam splitter attack strategy with a proper squeeze parameter.

Quantum key distribution using two-mode squeezd states

Acta Physica Sinica (2007)

Guangqiang He Yi Zhi Zhu Jun Guihua Zeng

A quantum key distribution scheme using two-mode squeezed states is proposed in this paper. The security of the proposed scheme against beam splitter attack is analyzed using Shannon information theory. The analytical expression of the secret information rate is given in terms of squeezed factor and channel parameters. The mode-mode correlation of two-mode squeezed states guarantees the security of the proposed scheme.
