Linearity Characteristics of Gate-Stack DG-MOSFETS: A Study with Diverse Biomolecule Configurations

In this study, we investigate the performance of gate-stack double-gate metal-oxide-semiconductor field-effect transistors (DG-MOSFETs) in the context of their application as biosensor devices. The analysis focuses on the impact of various biomolecules, including aptes, biotin, protein, and streptavidin, on the suggested biosensor system's linearity and overall effectivenessThe study systematically evaluates the influence of these biomolecules on the analog and linearity and sensitivity parameters such as gm2, gm3, VIP2, VIP3 and Id sensitivity of the Gate stack DG-MOSFET, comparing the results to establish a comprehensive performance profile. Our findings reveal that the Gate stack DG-MOSFET exhibits superior linearity compared to its symmetric counterpart. The unequal DG-MOSFET is more linear than the balanced one and the linearity of DG- M OSFE T can be enhanced by a changing channel thickness, doping concentration and different gate material. The study focus on the analog and linearity parameters of the purposed biosensor.
