In the present paper we have done a comparative analysis of Dual Gate MOSFET having split gate architecture and conventional Dual Gate MOSFET architecture. Simulations have been performed using SILVACO-ATLAS tool, which shows significant improvement in characteristic of split gate architecture in comparison to the conventional structure. The split gate architecture consist two different materials having different work functions placed laterally to form gate terminal of the MOSFET. This novel gate structure takes advantage of material work function difference in such a way that the threshold voltage near the source is more positive than that near the drain (for n-channel FET, the opposite for p-channel FET), resulting in high output impedance of the device.
