This study observes the MOSFET's performance concerning several biomolecules for use as a biosensor device. The double gate MOSFET with gate stack configuration has been chosen as the suggested device to surpass the limitations of short-channel effects (SCEs). The cavity was created to restrict the passage of charged and uncharged biological molecules so that they could be detected. These molecules fill the cavity, changing the device's electrical properties. The Double Gate MOSFET (DG-MOSFET) biosensor is subject to limitations such as Short Channel Effects (SCEs) and issues with the power supply. The suggested device decreased SCEs and it also demonstrates the potential benefits of having DG-MOSFETs with gate stacking for biosensor applications. Comparison of transconductance, the generating factor for transconductance, and sensitivity parameters such as Id and Vth sensitivity and Ion/Ioff sensitivity has been carried out in this study.
