摘　　要：设计了1种基于CMOS图像传感器列级处理的全摆幅信号读出电路,电路采用2个斜坡信号发生器和简单的电路单元,可实现全摆幅信号读出和数模转换,电路采用Global Foundries 0.35μm工艺设计,经仿真验证,电路可实现全摆幅信号读出和8位转换精度,INL/DNL<±0.2 LSB.A novel rail to rail readout circuti based on column-level processing was proposed. The circuit achieved rail to rail signal readout and analog to digital convertor by using two ramp signal generators and simple circuits. The readout circuit was designed by Global Foundries 0.35 um technology, and the test results indicated that the circuti can achieve rail to rail signal readout and 8-bit conversion accuracy with INL/DNL 〈± 0.2 LSB.
