一个组合的线性和对数图像传感器是在0.35 /spl mu/m 1 P3 M技术实现的。像素为7.5/spl times/7.5 /spl mu/m/sup 2/，填充因子为37%，仅包含4个晶体管。在对数区的偏移校准是通过使用电荷注入到光电二极管实现的。该传感器可实现120 dB DR，失调校准可将FPN从13 mV降至5 mV。
A combined linear and logarithmic image sensor is implemented in a 0.35 /spl mu/m 1P3M technology. The pixel is 7.5/spl times/7.5 /spl mu/m/sup 2/ with a 37% fill factor and contains only 4 transistors. Offset calibration in the logarithmic region is realized by using electrical charge injection into the photodiode. The sensor achieves 120 dB DR and the offset calibration reduces the FPN from 13 mV to 5 mV.
