Current Sensitivity and Power Dissipation Analysis of Junctionless Double Gate MOSFET Biosensor

Abstract

The paper demonstrates the sensitivity and power dissipation of a Junctionless N-type Double Gate MOSFET based biosensor over a wide range of temperature when neutral bio-analytes are introduced to its cavity region in the subthreshold region. The primary attention of this article is to highlight the current sensitivity of the biosensor (due to neutral as well as charged biomolecules) with respect to different parameters such as temperature, cavity length and power dissipation of the device. The device is simulated in sub threshold condition for both the cases of neutral as well as charged biomolecules to operate the device in low power and the same is discussed. All the simulations have been carried out in SILVACO ATLAS and the results are noted.
