Abstract
We present a monolithic ultraviolet (UV) image sensor based on a standard CMOS process. A compact UV sensitive device structure is designed as a pixel for the image sensor. This UV image sensor consists of a CMOS pixel array, high-voltage switches, a readout circuit and a digital control circuit. A 16 × 16 image sensor prototype chip is implemented in a 0.18 μm standard CMOS logic process. The pixel and image sensor were measured. Experimental results demonstrate that the image sensor has a high sensitivity of 0.072 V/(mJ/cm2) and can capture a UV image. It is suitable for large-scale monolithic bio-medical and space applications.-
