Abstract :
This paper presents a novel CMOS electric-field sensor, it is called the "differential electric-field sensitive field-effect transistor" (DeFET), which is based on a standard 0.18-mum Taiwan Semiconductor Manufacturing Company (TSMC) CMOS technology. The DeFET shows a sensitivity of 51.7 mV/(V/mum). This paper also describes the DeFET\´s theory of operation in addition to the experimental and simulation results that confirm the DeFET\´s theory of operation. Some applications of the DeFET in the area of lab on a chip and biomedical are also presented
