Abstract
In this paper, the digital and analog performance for Double Material Gate Surrounding Gate Metal Oxide Semiconductor Field Effect Transistor (DM SG MOSFET) has been analyzed. A detailed study of DM SG MOSFET is performed for different channel length ratio's. The comparison analysis on surface potential, electric field, transfer characteristics, output characteristics, transconductance and output conductance is carried with respect to the silicon dioxide and hafnium dioxide based device. It has been found from the simulation results that HfO2 dielectric used DM SG TFET provides better performance than SiO2 dielectric used DM SG TFET. Also it has been observed from the presented results that the transconductance is 45.32 at 1:3 channel length ratio for DG SG MOSFET.
