The constraints to manage in a telecom splitter design are numerous and according to a given splitter structure, the choice became difficult. The paper proposes a software tool allowing the design of such filters. This one carries out the modelling of the electrical circuit configurations, and creates the corresponding computation code, used for simulation or optimisation. The methodology is detailed...
This paper considers a size constrained version of the undirected feedback vertex set problem motivated by placing wavelength converters on a WDM network efficiently, and proves that this problem is NP-complete even in several special cases. Moreover, the paper presents a simple approximation algorithm for a minimization version of the problem using an algorithm for the original minimum undirected...
This paper presents a methodology to design and to optimize inductive power link for biomedical applications. The importance of the operation frequency on the application is expressed. A model of inductive link is presented. The dimensions of the coils are compatible with the size of a mouse and the mouse cage. The simulation results are in good agreement with the analysis.
The purpose of this work is to optimize the design of an MSK modulator able to operate at a high data modulation. The optimization approach applies an experimental design methodology having in view to minimize the modulator response time. This methodology is traditionally applied by agronomists and chemists. We show how it can be perfectly suited to optimize electronic designs.
Inductors play an essential role in the design of RF circuits. The parasitic effects plaguing integrated planar inductors require an accurate modeling and the careful exploration of their performance trade-offs. In this paper, a multi-objective performance modeling technique of planar inductors is presented, that supports both top-down and bottom-up design of RF circuits.
This brief proposes a novel multi-objective heuristic. It is a transformation of a mono-objective heuristic into a multi-objective one by addition of an archive and some non dominance computing routines. Performances of the proposed heuristic are demonstrated thru test functions. An application to the optimal sizing of a class AB second generation CMOS current conveyor is presented. Comparison with...
Refined Oil demand has great influence on the planning, operation and control of Refined Oil systems. A combined forecasting model based on the principle of gray theories was put forward to optimize Refined Oil demand forecasting models. The example shows that combined gray forecasting model can overcome the disadvantages of individual model, raise the precision.
A joint power system state and topology estimator based on a combined Weighted Least Squares (WLS) and Weighted Least Absolute Value (WLAV) strategy is proposed. The resulting coestimation algorithm is devised to simultaneously provide estimates to the analog power system variables and validate the current topology of the electric network. This is accomplished by formulating state & topology coestimation...
Analog circuit sizing is the task to determine the sizes of all components in the circuit during automated synthesis. Randomized combinatorial optimization algorithms are desired for quicker determination of a set of optimal sizes of the components. These algorithms require set of multiple performance parameters, for a very large number of sized circuits. Therefore the reduction in time required to...
This paper presents an improved crosstalk 2pi model for noise constrained interconnects optimization. The proposed model has simple closed-form expressions, which is capable of predicting the noise amplitude and the noise pulse width of an RC interconnect as well as coupling locations (near-driver and near-receiver) on victim net. This is efficient and sufficiently accurate to be effectively incorporated...
A Rectifying Antenna (Rectenna) is one of the most important components for a wireless power transmission. It has been developed for many applications such as Space Solar Power System (SSPS), Radio Frequency IDentification (RF-ID), and electric vehicle etc. The Rectenna consisting of RF-DC conversion circuits and receiving antennas needs to be designed for high conversion efficiency to achieve efficient...
