Leakage Modeling and Flat Field Correction Algorithm for CMOS Hyper Spectral Imaging Sensor

Using a combination of genetic algorithm and particle swarm optimization algorithm for GEMTIP modeling of spectral-induced polarization data

The generalized effective-medium theory of induced polarization (GEMTIP) is a newly developed relaxation model that incorporates the petro-physical and structural characteristics of polarizable rocks in the grain/porous scale to model their complex resistivity/conductivity spectra. The inversion of the GEMTIP relaxation model parameter from spectral-induced polarization data is a challenging is...

Subthreshold Leakage Modeling and Estimation of General CMOS Complex Gates

A new subthreshold leakage model is proposed in order to improve the static power estimation in general CMOS complex gates. Series-parallel transistor arrangements with more than two logic depth, as well as non-seriesparallel off-switch networks are covered by such analytical modeling. The occurrence of on-switches in off-networks, also ignored by previous works, is considered in the proposed a...

A 0.0016 mm2 0.64 nJ Leakage-Based CMOS Temperature Sensor

This paper presents a CMOS temperature sensor based on the thermal dependencies of the leakage currents targeting the 65 nm node. To compensate for the effect of process fluctuations, the proposed sensor realizes the ratio of two measures of the time it takes a capacitor to discharge through a transistor in the subthreshold regime. Furthermore, a novel charging mechanism for the capacitor is pr...

Biologically-inspired data decorrelation for hyper-spectral imaging

Hyper-spectral data allows the construction of more robust statistical models to sample the material properties than the standard tri-chromatic color representation. However, because of the large dimensionality and complexity of the hyper-spectral data, the extraction of robust features (image descriptors) is not a trivial issue. Thus, to facilitate efficient feature extraction, decorrelation t...
