This paper deals with the analysis of characteristic dispersions of CMOS-like logic gates (NOT, NAND2, NOR2) based on carbon nanotube transistors. The analysis is based on available compact models and uses a specific tool. We have simulated and analyzed the impact of diameter variations on the static and dynamic characteristics of gates, especially...

This paper examines aspects of design technology required to explore advanced logic-circuit design using carbon nanotube field-effect transistor (CNTFET) devices. An overview of current types of CNTFETs is given and highlights the salient characteristics of each. Compact modeling issues are addressed and new models are proposed implementing: 1) a p...

This paper provides an overview of current types of CNTFETs and of some compact models. Using the available models, the influence of the parameters on the device characteristics was simulated and analyzed. The conclusion is that the tube diameter influences not only the current level, but also the threshold voltage of the CNTFET, while the contact...

The aerodynamic design method for turbomachine blades reported in part 1 (Dang, T., and Isgro, V.,"Euler-Based Inverse Method for Turbomachine Blades Part 1: Two-Dimensional Cascades," AIAA Journal, Vol. 33, No. 12, 1995, pp. 2309-2315) is extended to three dimensions. In this inverse method, the blade pressure loading (i.e., pressure difference be...

The use of a full 3D and viscous inverse method for turbomachine blading with splitter blades is demonstrated by carrying out a design modification of a transonic axial stator blade row with splitter blades. In this design modification study, the goal is to improve the aerodynamics of the full blade and the splitter blade, including weakening of sh...

The practical utility of a three-dimensional inverse viscous method is demonstrated by carrying out a design modification of a first-stage rotor in an industrial compressor. In this design modification study, the goal is to improve the efficiency of the original blade while retaining its overall aerodynamic, structural, and manufacturing characteri...

A full 3D Navier-Stokes supersonic mixing layer HPF code is studied. The solver consists of a Roe's Riemann solver with TVD limiter and Strang splitting technique. A mesh size up to 512x512x64 has been run on a IBM RS-6000 SP2 in the Cornell Theory Center(CTC) using 256 nodes. The speedup is very encouraging. The results suggest that the large-scal...
