We report on a CMOS ASIC especially taylored for the differential read-out of ISFET sensors, to be used for remote monitoring of water pollution and for biomedical diagnostic and analysis. The circuit design is based on switched-capacitors technique, which allows a high resolution to be achieved. The first chip prototypes have been fabricated in 0.8 m, 5V CMOS technology, and are currently being tested. Preliminary results from the electrical characterisation of the chip are reported, which validate the design approach

Abstract
We report on a CMOS ASIC especially taylored for the differential read-out of ISFET sensors, to be used for remote monitoring of water pollution and for biomedical diagnostic and analysis. The circuit design is based on switched-capacitors technique, which allows a high resolution to be achieved. The first chip prototypes have been fabricated in 0.8 m, 5V CMOS technology, and are currently being tested. Preliminary results from the electrical characterisation of the chip are reported, which validate the design approachFile in questo prodotto:
