SOI p-MOS Biosensor Circuit-Layout Simulation

The paper presents a new biosensor design for protein detection. An electric circuit is proposed on the basis results of technological and circuit-layout simulation of the biosensor. In this design, a capacitor, one side of which is a sensitive region, serially connected to the gate of the amplifier transistor. The simulation results show that the developed biosensor has a high sensitivity and linear dependence of the output voltage on the potential of the information signal.
