As short channel effect (SCE) and subthreshold leakage is demonstrated to be controlled effectively from conventional planar MOSFETs to the FinFET, we used a three-dimensional simulation of nFinFET structure to analysis fin width effect on the FinFET performance from perspectives of both on-state and off-state. In this study, the major leakage path of FinFET with varied Wfin takes place at middle...
Based on the Gummel-Poon (GP) model, a simple and physical-based large-signal model for GaInP/GaAs heterojunction bipolar transistors (HBTs) is presented in this paper. We improve the current and transit time model by considering the potential spike effect and negative differential mobility. Different from the UCSD HBT and AgilentHBT models, only 46 parameters are used in our model. The DC characteristics...
We introduce a tool for organizing images and drawings of archaeological sites. The tool is based on a 3D sketching system developed for conceptual architectural design. The sketching system for design allows a user to represent structures as strokes located on 2D canvases situated in 3D space. The design of a consistent 3D structure evolves as the user is allowed to move the strokes from the 2D canvases...
Now all kinds of 3D virtual worlds have been popular on Internet, but due to gigantic data of virtual scenes and limit network bandwidth, traditional Client/Server based downloading scheme has been bottleneck for a user to construct local virtual worlds swiftly. This paper proposes a parallel delivery scheme for large scale virtual scenes in a two-layer hybrid based P2P(Peer-to-Peer) overlay, in which...
