Abstract

This paper proposes a novel single-poly floating gate (FG) UV sensor in standard CMOS process. The sensor cell is based on PMOS FG and only adopts four transistors including sensitive component and readout amplifier. The architecture is compact and feasible for future high density array chip implementation. A theoretical analysis of sensor sensitivity is described in detail. As the sensor is compatible with standard single poly CMOS process, it has the merits of low cost, more sensitive, and be integrated with signal processing system. A prototype chip is manufactured in a 0.18μm single-poly standard CMOS logic process. The tested results indicate that the sensor is sensitive to the incoming UV irradiation.
