Design of a dual band-pass filter using modified folded stepped-impedance resonators
(Institute of Electrical and Electronics Engineers, 2009)
A folded stepped impedance resonator (SIR) modified by adding an inner quasi-lumped SIR stub is used as the basic block of a new configuration of dual band-pass filter. The main advantage of the proposed filter is to allow ...

Model-based design for selecting fingerprint recognition algorithms for embedded systems
(2012)
Most of contributions for biometric recognition solutions (and specifically for fingerprint recognition) are implemented in software on PC or similar platforms. However, the wide spread of embedded systems means that ...

A complete retargeting methodology for mixed-signal IC designs
(Institute of Electrical and Electronics Engineers, 2001)
In this paper, an efficient methodology to retargeting and reuse of embedded mixed-signal blocks is presented. Parametrized layout templates, accurate behavioral modeling of mixed-signal blocks, and appropriate mechanisms ...

Circuit implementation of piecewise-affine functions based on lattice representation
(Institute of Electrical and Electronics Engineers, 2011)
This paper introduces a digital architecture to implement piecewise-affine (PWA) functions based on representation methods from the lattice theory. Given an explicit and continuous PWA function, the parameters required to ...

Multi-band high-impedance surface absorbers with a single resistive sheet: Circuit theory model
(Institute of Electrical and Electronics Engineers, 2011)
We present a simple and efficient circuit model for the analysis of multi-band absorption characteristics of a stack of sub-wavelength grids (fishnets or patch arrays) in a layered environment with a single resistive sheet ...

A 176x144 148dB adaptive tone-mapping imager
(Society of Photo-Optical Instrumentation Engineers, 2012)
This paper presents a 176x144 (QCIF) HDR image sensor where visual information is simultaneously captured and adaptively compressed by means of an in-pixel tone mapping scheme. The tone mapping curve (TMC) is calculated ...

NORFREA: An algorithm for non redundant fuzzy rule extraction
(Institute of Electrical and Electronics Engineers (IEEE), 2002)
This contribution presents a new algorithm (NORFREA) to select fuzzy rules from a grid partition of the input domain. Besides using an efficiency measure for the rules, this algorithm employs an heuristic technique ...

Efficient realization of RTD-CMOS logic gates
(2011)
The incorporation of Resonant Tunnel Diodes (RTDs) into III/V transistor technologies has shown an improved circuit performance: higher circuit speed, reduced component count, and/or lowered power consumption. Currently, ...

Equivalent circuits for conventional and extraordinary reflection in dipole arrays
(Institute of Electrical and Electronics Engineers, 2011)
This presents an equivalent transmission-line circuit that accounts for the scattering of a TE polarized plane wave that impinges obliquely on a periodic array of metallic patches sandwiched in a dielectric slab. The ...
