In this work, a gate underlap channel dielectric-modulated (DM) double-gate (DG) MOSFET which is working as biosensor for the label free electrical detection of the biomolecules has been investigated. The electrical characteristics such as, threshold voltage and drain current of DM DG MOSFET have been studied by the device simulation. The shift in the threshold voltage has been used as the sensing metric to detect the sensitivity after the biomolecules interacts with the device. four-gate NMOS inverter has also been used to investigate a label free electrical detection of the biomolecules. The work has been done under the consideration of dry environment condition.
