【Abstract】 Threshold voltage is the most important parameter of MOSFET. Threshold voltage model is the most important part of MOSFET model. Currently, the model parameters extraction is performed mainly through commercial software. The application of commercial software is confined because they are usually very expensive and their mechanism is too complex. A novel method combining genetic algorithm and local optimization is proposed in this paper to extract threshold voltage parameters of BSIM SOI. This method is simple and easy to use. And it has very good accuracy. It is convenient to apply to use.更多还原
