Abstract:  This paper presents a novel CMOS electric field sensor, termed as a Differential Electric Field Sensitive Field Effect Transistor (DeFET). It’s based on a standard 0.18μm CMOS technology. The DeFET shows a sensitivity of 76 μA/V/μm. Also, the DefET’s theory of operation is presented and discussed. Both the experimental and simulation results confirm the DeFET’s theory of operation is presented.
