Abstract(in English) | An ultra wide dynamic range (WDR) CMOS image sensor (CIS) integrating a high-speed column-parallel cyclic ADC with a built-in noise canceler is presented. The proposed signal readout technique of extremely short accumulation (ESA) enables the dynamic range of image sensor to be expanded up to 160dB. To achieve the high-speed high-quality signal readout required for the multiple exposure signals, column parallel A/D converters are integrated at the upper and lower sides of pixel arrays. An offset cancellation technique for the cyclic ADC is proposed to reduce column FPN of the image sensor in analog domain. The measured column FPN was reduced to 0.12% without any offset cancellation in digital domain. |
