英文摘要：

A CMOS image sensor with a novel reading out circuit is proposed. The circuit consists of four MOS transistors and one capacitance. The sensor is driven by two related plus and power consumption is less than 0,7mW. Video signal which can convert easily from analog to digital is output by single end. The sensor can achieve on-chip difference, In this paper, the theoretical analysis and simulation results of the circuit are given. A 256-pixel test device is designed by using the 1,2μm N-Well double poly double mental standard CMOS processes, Dimension of the chip is 1mm× 11mm with 25μm pixel distance. The measurement and analysis of the main parameters are implemented successfully and the device＇s function is verified.
