Abstract

The gm/ID theory was applied to systematically study the optimized operation regime of a fabricated Extended-Gate Field Effect Transistor (EGFET) with the hydrogen ion selective membrane (ISM) for amperometric pH sensing. Electrochemical Impedance Spectroscopy (EIS) and electrical characterization was conducted on the EGFET. With the parametric analysis in the IC CAD software (Cadence, USA) using Global Foundries 0.18µm 1P6M CMOS process, and normalized experimental data, the optimized operation regime of pH-EGFET was determined to give higher sensor output and higher normalized sensitivity.
