摘要: A new analytical two-dimensional model is developed that accurately predicts channel potential variation with external voltages and along the length of in subthreshold regime, including drain-induced barrier lowering (DIBL) effects GaAs MESFETs. Threshold voltage modified to account for short effects. The parameters important modelling drain current are calculated this provides basis a model. Moreover, models compared those Adams numerical analysis good agreement obtained.
