TCAD Modeling using a Neural Network Based Approach

Matei R., Dima G., Profirescu M.D., University Politehnica of Bucharest, RO

This paper presents system level modelling and simulations results of two closed loop, force-feedback control strategies for micromachined tunnelling accelerometers. The first approach is based on the incorporation of the sensing element in a sigma-delta [...]

HEMT Optimization by Advanced RSM Models

Profirescu M.D., Dima G., Govoreanu B., Mitrea O., University Politehnica of Bucharest, RO

In this paper, the optimization of heterostructure devices using the Design of Experiments concept and advanced Response Surface Models is presented. As an example, the structural optimization of a pseudomorphic Al0.2Ga0.8As/In0.2Ga0.8As/GaAs pulse doped HEMT is [...]
