ELECTROOPTICAL DEVICE MODELS FOR ELECTRICAL SIMULATORS

This paper describes the modeling for the analysis of electro-optical devices using a conventional electrical simulator. The proposed approa ch is intended for the analysis of optical sensor systems, which have optical and electronic devices integrated on the same silicon chip. Mo dels have been developed using a hardware description language for the following devices: the LED, the photodiode and the absorbing medium. Suitable approximations allow the models to be accurate with a limited number of parameters while the computation time is kept sufficiently short. Simulation results show good agreement between numerical analys is and experimental data previously reported in the literature.
