Solid-State Electronics, v. 49, n. 4, p. 1255-1261, 2005.0038-1101https://repositorio.fei.edu.br/handle/FEI/1253This work presents a new approach for the current model of thin-film, fully depleted SOI edgeless transistors, based on the asymmetric trapezoidal gate model. The most common current model for an edgeless transistor is obtained by taking the rectangular device drain current expression and substituting the device width by an "equivalent" device width, usually given by the average between source and drain width of the channel. However, this model does not take into account some effects that take place near the corners of the device and that have a significant influence on the current expression. The new model is tested using three-dimensional numerical simulation and experimental data. The proposed model is still simple and both simulation and experimental results show that it presents an improved performance. © 2005 Elsevier Ltd.
