Abstract:A new type of ISFET is proposed where the proposed ISFET channel is divided into a gatecontrolled region (Region gate and sensing region (Region sense. The ISFET is operated by controlling the gate voltage of the Region gate with the attached biomolecules on the gate dielectric of the Region sense. When the gate voltage is applied over the threshold voltage (V th , the channel resistance of the Region gate sharply decreases and the larger channel resistance of the Region sense limits the ISFET current. Thus, t… Show more
