Electro-thermal modeling of power LED using SPICE circuit solver
Catalin Negrea,Paul Svasta,Marius Rangu +2 more
- 09 May 2012
TL;DR: The presented approach offers three significant advantages over the traditional single-domain modeling: the effects of packaging and board level thermal management can be evaluated in correlation with electrical parameters, the self heating effect of the junction can be analyzed in the time domain, and the variation of luminous flux output can be observed.

Analysis of crosstalk effects on single ended signal lines crossing split reference planes
Marcel Manofu,Catalin Negrea,Roxana Vladua +2 more
- 01 Oct 2016
TL;DR: In this paper, the effects of a split reference plane on the crosstalk level between single-ended (SE) signal lines crossing the split were analyzed by investigating microstrip and stripline configurations for different plane split geometries through electromagnetic simulation and time-domain reflectometry (TDR).

PCB layout optimization for LED backlight module using FEM simulation
Aurelian Botau,Catalin Negrea +1 more
- 01 Oct 2013
TL;DR: In this article, the authors present a method of optimization for a LED matrix assembly, where the main purpose is to improve the thermal uniformity on the PCB in order to reduce the luminous flux output difference between the devices, while also maintaining the junction temperatures in the acceptable operating range.

Optimization of LED assembly for LCD backlight using photo-electro-thermal modeling and simulation
Catalin Negrea,Laurentiu Gabor,Paul Svasta +2 more
- 24 Dec 2012
TL;DR: The approach is to eliminate the need for custom made diffusers and PCB redesign by a more detailed evaluation on the LED behavior in the first design stages of the backlight assembly by defining a photo-electrothermal simulation model that can accurately predict luminous intensity based on electrical and thermal conditions.
