In the present work, the performance of DG-JL transistor has been analysed using analytical modeling scheme as well as 3D device simulation technique. Thus an advance two dimensional analytical subthreshold drain current model for Double Gate Junctionless (DG-JL) Transistor is presented in this work by considering the impact of fringing field from the gate to source/drain region using conformal mapping technique. The results obtained from proposed model have been verified with the ATLAS 3D device simulation software results. The relevant Short Channel Effect parameters like threshold voltage roll off, Drain Induced Barrier Lowering (DIBL) and Subthreshold Slope (S) are also evaluated using modeling scheme. In addition to this, the suitability of DG-JL Transistor for low voltage digital and analog applications has been investigated through exhaustive device simulation using ATLAS 3D device simulation software only. In essence, this work provides the dependencies of the device performance on the physical device parameters of DG-JL transistor for its assessment for better digital and analog operation.
