Improved Multiexponential Transcient Spectroscopy By Iterative Deconvolution
MetadataShow full item record
The analysis of multiexponential decays is challenging because of their complex nature. When analyzing these signals, not only the parameters, but also the orders of the models, have to be estimated. Here, we present an improved spectroscopic technique specially suited for this purpose. The proposed algorithm combines an iterative linear filter with an iterative deconvolution method. A thorough analysis of the noise effect is presented. The performance is tested with synthetic and experimental data.

Suboptimal Filtering and Nonlinear Time Scale Transformation for the Analysis of Multiexponential Decays Palacín Roca, Jordi; Marco, Santiago; Samitier, Josep (IEEE, 2001)Multiexponential decays may contain time-constants differing in several orders of magnitudes. In such cases, uniform sampling results in very long records featuring a high degree of oversampling at the final part of the ...
A Time-Domain Method for the Analysis of Thermal Impedance Response Preserving the Convolution Form Carmona, Manuel; Marco, Santiago; Palacín Roca, Jordi; Samitier, Josep (Institute of Electrical and Electronics Engineers, 1999)The study of the thermal behavior of complex packages as multichip modules (MCM’s) is usually carried out by measuring the so-called thermal impedance response, that is: the transient temperature after a power step. ...
Dynamic Compact Thermal Models With Multiple Power Sources: Application to an Ultrathin Chip Stacking Technology Palacín Roca, Jordi; Salleras, Marc; Samitier, Josep; Marco, Santiago (Institute of Electrical and Electronics Engineers, 2005)Whereas numerical modeling using finite-element methods (FEM) can provide transient temperature distribution in the component with enough accuracy, it is of the most importance the development of compact dynamic thermal ...
