Theoretical Investigation of Dual Material Junctionless Double Gate Transistor for Analog and Digital Performance.

In this paper, we report the 2-D drain current model for asymmetric dual material (DM) junctionless double gate transistor. On the basis of channel potential, transconductance and its higher order derivatives are estimated and verified with the ATLAS 3-D device simulator results. The developed model is also applicable to investigate the digital performance of the device in terms of voltage transfer characteristics of nMOS inverter circuit. The impact of the length of control gate on the analog performance has also been investigated. Results also highlight the advantage of DM gate over the single material gate for digital and analog applications using CMOS inverter and common source amplifier through exhaustive circuit simulation.
