IETR has been developing for several years a set of CAD tools for the analysis, the synthesis and the optimisation of millimetre-wave shaped dielectric lens antennas. These tools are complementary and are based on various formulations based on ray tracing, Geometrical Optics / Physical Optics, Finite-Difference Time-Domain techniques, and modal expansion techniques. Several of them have been combined...
Future aircrafts start seeing the replacement of their existing metal skin by composite materials. The emergence of these new materials in this environment requires a paradigm shift in the electrical network design, especially regarding the current return path. The composite fuselage cannot comply anymore with all the functionalities of the current aluminum skin because of the imposed maximum admissible...
As CMOS technology scales down into the deep-submicron domain, the cost of design, complexity and customization for Systems-On-Chip (SoCs) is rapidly increasing due to the inefficiency of traditional CAD tools. In this paper we present a new interactive refinement algorithm in high-level synthesis, based on dynamic programming, which maximizes resource optimization in data path. We start by quantifying...
In this paper an automation tool is proposed for OTA designs. The core of the tool is a combination of a mathematical tool and a circuit simulator. The automation tool contains four libraries: OTA topologies, technology parameters, performance limits and design constraints. Design of typical OTA topologies can be implemented in three fabrication technologies. The user introduces OTA specifications...
Display is the most power-hungry component in electronics industry. Power-efficient design is strongly required in thin film transistor liquid-crystal display (TFT-LCD) portable products. This work proposes a unified parameterization technique for modeling and multi-objective optimization of TFT-LCD panel using a two-stage response surface model (RSM) and genetic algorithm (GA). To achieve designing...
