Abstract :
In this paper, general analytical models for threshold voltage Vt and subthreshold slope S of single gate (SG), symmetric double gate (DG) and ground plane (GP) MOSFETs are proposed. The effect of channel strain on Vt¿ S and drain induced barrier lowering (DIBL) is also investigated. The proposed model has been employed to calculate Vt¿ S and DIBL for various MOS structures. Additionally simulation has been performed using ATLAS, a 2D numerical device simulator. Accuracy of models has been verified by comparing analytical results obtained from proposed models with the simulated data and a few reported experimental results.
