In this letter, a simulation based investigation has been done to calculate the sensitivity of the gate underlap Junctionless (JL) Double Gate (DG) MOSFET for label free electrical detection of the biomolecules. The impact of biomolecules has been investigated of the various electrostatic characteristics of the JL DG MOSFET. The simulation has been carried out with the help of Sentaurus Device Simulator tool. The underlying Gate underlap JL DG MOSFET has been virtually fabricated by using Sprocess tool of Sentaurus.
